15.034 [B&F: 0315] Phyllonorycter harrisella (Linnaeus, 1761) - Common

Common in oak woodland and areas with scattered oaks throughout Britain, widespread but apparently less frequent in Ireland. In Hampshire and on the Isle of Wight widespread and common. Wingspan 7-9 mm. Imago fairly regular at light, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of deciduous oaks Quercus, over-wintering as a pupa in a cocoon.

15.036 [B&F: 0317] Phyllonorycter heegeriella (Zeller, 1846) - Common

Common in oak woodland and areas with scattered oak trees throughout England, Wales and Scotland, except in the far north; commonest in southern England but rare in Ireland. Although not recorded in Hampshire until 1976, it is now widespread; first recorded on the Isle of Wight in 2005. Wingspan 6.5-7.5 mm. Similar to P. tenerella, which lacks the distinctly dark-bordered basal streak, although it occasionally has an ochreous base to the wing with a white central streak extending through this coloration (MBGBI Vol 2). Imago fairly regular at light, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of deciduous oak Quercus, over-wintering as a pupa in a cocoon.

15.037 [B&F: 0318] Phyllonorycter tenerella (Joannis, 1915) - Local

Local in woodland throughout much of south-eastern England, found elsewhere as an introduction in Hornbeam plantations. In Hampshire apart from one old record from Alice Holt in 1963, recorded only since 1998, mostly by Rob Edmunds around Fleet, but also near Bentley and Odiham in north Hampshire and at Lower Test Marsh in south Hampshire. Recorded on the Isle of Wight for the first time at Osborne in 2010. Wingspan 6-8 mm. Imago may come to light, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Hornbeam, over-wintering as a pupa in a cocoon.

15.039 [B&F: 0320] Phyllonorycter quercifoliella (Zeller, 1839) - Common

Common in oak woodland and areas with scattered oaks throughout much of the British Isles, except for the Northern Isles. In Hampshire and on the Isle of Wight widespread and locally common to abundant, but perhaps declining. Wingspan 7-9 mm. Similar to P messaniella, in which the basal streak barely reaches middle of wing, terminating well before the apices of the first pair of strigulae. In P quercifoliella the apical streak extends to almost two-thirds and terminates slightly beyond the apices of the first pair of strigulae (MBGBI Vol 2). Imago fairly regular at light, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of deciduous oaks Quercus, over-wintering as a pupa in a cocoon.

Common in woodland throughout much of the British Isles, more numerous in the south. Abundant in Hampshire and on the Isle of Wight. Wingspan 7-9 mm. Very similar to P quercifoliella, which see for differences. Although the imago is fairly regular at light, just as likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Oak, especially Evergreen Oak, Hornbeam, Beech and Sweet Chestnut.

15.041 [B&F: 0321a] Phyllonorycter platani (Staudinger, 1870) - Local

Local in parks and urban areas, discovered new to Britain in London in 1990, since when it has spread through the southern counties of the UK and has reached the West Country and Midlands. Found in Hampshire for the first time in 1998 in Southampton and on the Isle of Wight in 2004, becoming more frequent and widespread. Wingspan 9-10.5 mm. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of London Plane in late autumn and are large and obvious, one leaf often hosting several, over-wintering as a pupa in a cocoon.

15.053 [B&F: 0332a] Firethorn Leaf Miner Phyllonorycter leucographella (Zeller, 1850) - Common

Common in gardens, woodland and parkland throughout much of Britain. Thoroughly naturalised, through accidental introduction in garden plants, the first British record of this adventive species was in Essex in 1989, since when it has spread rapidly northwards to Yorkshire. It was first discovered in Hampshire in early 1998, but probably under-recorded in the county and on the Isle of Wight, where the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 6.5-8.5 mm. Imago fairly regular at light, but just as likely to be recorded in the larval stage, when mines are relatively easy to find where they are present.

15.054 [B&F: 0333] Phyllonorycter salictella (Zeller, 1846) - Common

Common in marshes, river-banks and other damp areas in England and Wales, with scattered records in Scotland; rare in Ireland. In Hampshire and on the Isle of Wight locally common in the south-east of the county and around Fleet, and probably under-recorded elsewhere. Wingspan 7.5-8 mm. Imago fairly regular at light, but more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of smooth-leaved Salix species, such as Osier and Crack Willow, has also been recorded on Aspen, over-wintering as a pupa in a cocoon.

15.064 [B&F: 0342] Nut Leaf Blister Moth Phyllonorycter coryli (Nicelli, 1851) - Common

Very common in woodland, scrub and hedgerows throughout much of the British Isles, except for the Northern Isles. In Hampshire and on the Isle of Wight abundant wherever hazel occurs (it likely occurs in virtually every 1-km square in the county where hazel grows). The mine is one of the most easily found in the autumn countryside, forming a silvery, upper-side blotch, crossing veins and there may be multiple on the same leaf. The mine may contract later to cause leaf to fold upwards. The adult moth, like many Phyllonorycter species, is less distinctive and unless bred from a mine, records will require dissection for acceptance: given the ease of identification at the larval stage, this is probably not worthwhile.

15.065 [B&F: 0343] Phyllonorycter esperella (Goeze, 1783) - Local

Local in woodland in south-east England up to Northamptonshire, with isolated records elsewhere from the south-west and Welsh borders (MBGBI Vol 2). Probably under-recorded in Hampshire, where the extent of known records correlate with those areas in which the recording effort is concentrated, with the first record from the Isle of Wight coming in 1996. Wingspan 7.5-9 mm. Imago not often seen at light, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present; in Hampshire and on the Island, almost all records are of the leaf mines, hence the sparseness of the flight-time graph. Larva mines leaves of Hornbeam, over-wintering as a pupa in a cocoon.

15.067 [B&F: 0345] Phyllonorycter rajella (Linnaeus, 1758) - Common

Common in damp woodland throughout much of the British Isles. In Hampshire and on the Isle of Wight apparently well-distributed, but like many leaf miners, probably under-recorded in north Hampshire away from the M3 corridor, and in the New Forest. Wingspan 7-9 mm. Imago does not readily come to light, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Alder and Italian Alder, over-wintering as a pupa in a cocoon.

15.070 [B&F: 0348] Phyllonorycter quinqueguttella (Stainton, 1851) - Nationally Scarce B

Nationally scarce (Nb) on sand-dunes and heaths, mainly in coastal counties of Britain. In Hampshire restricted to Emer Bog, a few boggy areas in the New Forest and more recently in the north of Hampshire (albeit in VC22). Not recorded from the Isle of Wight to date. Wingspan 6-7.5 mm. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Creeping Willow, over-wintering as a pupa in a cocoon.

Record Details

15.074 [B&F: 0352] Phyllonorycter schreberella (Fabricius, 1781) - Common

Common in hedgerows throughout much of England and Wales. Reasonably common in south-east Hampshire and on the Isle of Wight, but elsewhere in the county distinctly uncommon. Wingspan 6.5-7.5 mm. Almost always recorded in the larval stage, when the mines are fairly easy to find where they are present, the adult can be separated from other similar Phyllonorycter species on external features only with great care. Larva mines leaves of Elm, over-wintering as a pupa in a cocoon.

15.075 [B&F: 0353] Phyllonorycter ulmifoliella (Hübner, [1817]) - Common

Widespread and common in birch woodland, with most records being of the leaf mine. Wingspan 7-9mm. Forewing golden-brown, with four costal and three dorsal white strigulae, dark edged inwardly, with a white dark-edged basal streak to one-third. The first pair of strigulae meet to form a slightly curved fascia; dorsal strigulae 2 and 3 lie between the remaining three costal marks, the second pair nearly meeting to form a second fascia, as can the third pair. Sometimes has a pale dorsal patch between the base and the first fascia.

The larva mines the underside of Birch leaves; a small mine, 8-14mm long, causing the upperside to appear dried-up and brownish, the underside with several folds which coalesce to give the appearance of a larger central fold. The leaf is often contorted and curves downwards. Mines can be found in June/July and more plentifully during autumn.

15.076 [B&F: 0354] Phyllonorycter emberizaepenella (Bouché, 1834) - Local

Local, in woodland, scrub and hedgerows, throughout Britain, rarely in Ireland. In Hampshire and on the Isle of Wight there are only scattered records, although possibly under-recorded. Wingspan 9-10mm. Forewing has a ground colour of light brown. There are four costal and five dorsal white strigulate, the first two pairs meeting to form distinct fascia, the first of which is irregular and varying in width, and the second pair form an obtuse angled or smooth outward-facing fascia; the third pair nearly meet at an acute angle; the fourth pair are opposite and separated from the third by a small patch of dark brown scales; dorsal 5 is immediately below apical patch. The basal streak is short and sinuate, reaching first fascia, and fascia are lightly edged with brown.

The larva mines leaves of Honeysuckle and Snowberry, forming a very large mine underside the leaf: the lower epidermis is gathered into strong folds puckering the leaf, but it does not twist as per P. trifasciella. The moth is bivoltine, generally flying in spring and late summer.

15.078 [B&F: 0356] Phyllonorycter tristrigella (Haworth, 1828) - Common

Common in hedgerows in England and Wales. In Hampshire mines are widespread and common on Elm in both vice-counties, and evidently also widespread on the Isle of Wight. Wingspan 7.5-8.5 mm. Imago differs from P. stettinensis, P. froelichiella, P. nicellii and P. kleemannella in having the white pattern much less metallic and its black edging fading more evenly into the ground colour. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Wych Elm, English Elm and Small-leaved Elm, over-wintering as a pupa in a cocoon.

15.079 [B&F: 0357] Phyllonorycter stettinensis (Nicelli, 1852) - Common

Common in damp woodland throughout much of England and Wales, and parts of western Scotland. Probably under-recorded in Hampshire or on the Isle of Wight, where the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 6.5-7.5 mm. Imago similar to P. tristrigella, P. froelichiella, P. nicellii and P. kleemannella, but the only one of the group to have a blackish brown vertical tuft on the head. P. stettinensis may also be distinguished by its short basal streak; P. tristrigella usually has a pale basal spot, but the other species no indication even of this (MBGBI Vol 2). Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Alder, over-wintering as a pupa in a cocoon.

15.080 [B&F: 0358] Phyllonorycter froelichiella (Zeller, 1839) - Common

Common in damp woodland throughout much of Britain, but in Ireland known only from the Burren. Probably under-recorded in Hampshire and on the Isle of Wight, where the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 9-10 mm. Imago similar to P. stettinensis, P. tristrigella, P. nicellii and P. kleemannella, but is by far the largest species in the group, its copper-brown ground colour is characteristic, it has the narrowest and most sharply defined black edging to the white markings and the first pair of strigulae are smoothly curved distad with their apices almost touching to form an acute- or right-angled chevron (MBGBI Vol 2). Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Alder, over-wintering as a pupa in a cocoon.

15.081 [B&F: 0359] Phyllonorycter nicellii (Stainton, 1851) - Common

Common in woodland throughout much of the British Isles, but more plentiful in the south. In Hampshire and on the Isle of Wight widespread and common. Wingspan 7-8 mm. Imago similar to P. stettinensis, P. tristrigella, P. froelichiella and, especially, P. kleemannella. P. kleemannella and P. nicellii are two of the more difficult of the group to distinguish. P. kleemannella has a deeper orange ground colour, the fasciae are more shining and often bordered inwardly by a broad band of deep coppery brown rather than the brown irroration of P. nicellii; the first pair of strigulae rarely meet. In P. nicellii the first pair of strigulae often touch, forming a third angulated fascia (MBGBI Vol 2). Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Hazel, over-wintering as a pupa in a cocoon.

15.082 [B&F: 0360] Phyllonorycter klemannella (Fabricius, 1781) - Common

Common in damp woodland throughout Britain, except southern Scotland; in Ireland recorded only from Cos Kerry and Wicklow. Probably under-recorded in Hampshire and on the Isle of Wight (where it was first discovered in 1996): the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 8 mm. Imago similar to P. stettinensis, P. tristrigella, P. froelichiella and, especially, P. nicellii, which see for differences. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present.

Common in woodland and hedgerows throughout England and Wales, more local in Scotland and apparently only coastal in Ireland (MBGBI Vol 2). In Hampshire and on the Isle of Wight common and widespread. Wingspan 7-8 mm. Imago fairly regular at light, but just as likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Honeysuckle Lonicera periclymenum, but also Leycesteria formosa and Symphoricarpos.

15.084 [B&F: 0362] Phyllonorycter acerifoliella (Zeller, 1839) - Common

Common in woodland and hedgerows in south Wales and England, as far north as Derbyshire, with isolated records in Northumberland and Westmorland (MBGBI Vol 2). In Hampshire and on the Isle of Wight common and fairly widespread. Wingspan 8 mm. Imago similar to P. platanoidella, in which the dorsal strigula forming part of the rudimentary first fascia does not nearly touch and make a straight fascia with the second costal strigula as in P. acerifoliella; the second fascia forms an obtuse angle or a smooth curve, whereas in P. acerifoliella it forms an acute or right angle; the yellow-brown coloration of the pattern is deeper than on P. acerifoliella (MBGBI Vol 2). Also similar to P. geniculella, which see for differences. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Field Maple, over-wintering as a pupa in a cocoon.

15.085 [B&F: 0363] Phyllonorycter joannisi (Le Marchand, 1936) - Common

Common in woodland and hedgerows throughout much of south-eastern England and in Worcestershire, but expanding northwards and has recently been found as far north as Yorkshire (MBGBI Vol 2, UKMoths). First discovered in Winchester (vice-county 11) in 1977, spreading to vice-county 12 at Leckford seven years later and the Isle of Wight (vice-county 10) in 2000. Now fairly widespread across both counties, although rare in the New Forest. Wingspan 8 mm. Imago similar to P. acerifoliella and P. geniculella. Imago only occasionally encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva monophagous, mining leaves of Norway Maple and over-wintering as a pupa in a cocoon.

15.086 [B&F: 0364] Phyllonorycter geniculella (Ragonot, 1874) - Common

Common in woodland and hedgerows throughout much of Britain, but not in northern Scotland. In Hampshire and on the Isle of Wight fairly well distributed, but perhaps under-recorded in north Hampshire away from the M3 corridor and in the New Forest. Wingspan 8 mm. Similar to P. acerifoliella and P. platanoidella, but differs in having the second chevron sharply angled with its apex extended as a dark-bordered yellow line to the third chevron; the rudimentary first chevron at the base of the wing contains more yellowish brown scales than either of the other two species (MBGBI Vol 2). Imago relatively uncommon at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Sycamore, over-wintering as a pupa in a cocoon.

15.087 [B&F: 0365] Phyllonorycter comparella (Duponchel, [1843]) - Nationally Scarce A

Scarce in damp woodland throughout England. Wingspan 8 mm. Larva mines leaves of White Poplar and Grey Poplar, often favouring isolated, young saplings. In Hampshire first identified as a mine on poplar leaves at Butterwood near Hook, VC12 in 2007 (also reported from the Hants/Surrey border in 2021); subsequently found to be locally common in the Portsmouth area with records from 2019 to date. Not recorded from the Isle of Wight to date.

15.089 [B&F: 0366a] Cameraria ohridella Deschka & Dimic, 1986 - Common

Common in parks and urban areas throughout much of south-eastern England. An adventive species, first recorded in Europe in Macedonia in 1995, from where it has spread rapidly. In Britain, first recorded in Wimbledon, London in 2002, reaching plague proportions around Greater London and along the Thames Valley by 2006. The first record in Hampshire occurred in 2004, and it appears that it is being dispersed along railway lines and major roads, and now widespread and abundant across much of the county and on the Isle of Wight. Wingspan 8 mm. The larva mines the leaves of Horse Chestnut causing noticeable brown blotches, often many to one leaf, often resulting in complete defoliation of a tree, over-wintering as a pupa in a cocoon. There is however, a similar-looking fungus which can cause confusion.
