The Olethreutinae is a subfamily of the Leafrollers (Tortricidae), of which about 4400 species have been described worldwide. It is a monophyletic group, a group of organisms that are believed to have all the same common ancestor that is itself included in the taxon and all of which descendants are placed in the same group. The Olethreutinae is a sister group of the Tortricinae. The primary food source is from 1 plant family with which they are oligophagous. The eggs are laid individually or in small groups. The hatched larvae mainly bore into fruit, roots, stems, and shoots of plants.

Meadow Hook-wing – 2024 (CH)
(NCBI-index: 1.594232)
You must pay close attention to the forewing pattern to identify the Meadow Hook-wing (Ancylis badiana). It looks very similar to the Fen Roller (Ancylis paludana). The Meadow Hook-wing is darker and has a narrower cream-coloured band along the leading edge. A striking difference is the number of black dots at the base of the fringe line near the wing tip. This is never more than 1 in the Meadow Hook-wing, while in the Fen Roller, this is 3 or 4. The forewing ends in a broad lobe, which makes it look like a hook. From above, you can see the dark brown triangle with the point close to the head and the base halfway along the wing. The flight period is two generations from April to October, and the wingspan is 12-16 mm. Host plant: Vetch, Clover. Dutch name: Bonte haakbladroller. Frisian name: –

Thistle Bell – 2017 (NL)
(NCBI-index: 1.100980)
The Thistle Bell (Epiblema scutulana) is a moth that is very difficult to distinguish from the Southern Thistle Bell. It is a reasonably dark moth with a noticeable white spot in the centre of the wings. This is best seen when the moth is in a resting position. It looks like a saddle to which it owes its Dutch name. In some specimens, you can see that the white spot is more of a white band. Flight time is from May to June in one generation, and the wingspan is 18-23mm. The larvae live in the stems and roots. Host plant: Musk Thistle and Spear Thistle. Dutch name: Distelzadelmot. Frisian name: –

White-foot Bell – 2020 (NL)
(NCBI-index: 1.100979)
The most striking thing about the White-foot Belle (Epiblema foenella) is the white, sometimes grey, curved spot near the dorsum. Above, it looks like a white horseshoe or bell on the purple-brown forewing to red-brown forewing. Near the tornus is a pale round spot with often three or four black or brown dots. Sometimes, the white marking is also missing. The flying period is from the end of June to September in one generation, and the wingspan is 17-26mm.

Brown Elm Bell – 2023 (NL)
(NCBI-index: 1.594292)
Contrary to what one might initially think based on the Dutch name, it has nothing to do with the colour of the eyes. The “eye” refers to a dark spot on the forewing near the wing tip. This is often brown, black, or dark orange, such as for the Brown Elm Bell (Epinotia abbreviana). The Brown Elm Bell is variable in colour and markings. The forewing is orange-brown to dark red-brown with a creamy white or yellow-brown transverse band on a 1/3, making an acute angle inward halfway. Another narrow white band runs towards the leading edge from the inner edge corner, covered with silver-coloured scales. At the leading edge, you can also see several paired white bands that are particularly noticeable near the wing tip. The flight period is one generation from May to August, and the wingspan is 12-16mm. Host plant: Elm. Dutch name: Oranje oogbladroller. Frisian name: –

Common Rose Bell – 2021 (NL)
(NCBI-index: 1.594313)
The forewing of the Common Rose Bell (Notocelia roseacolana) is white and partly spotted with lead grey, especially the wing base. Along the leading edge from the wingtip to halfway, you see dark grey triangular spots with narrow grey, sometimes light brown, narrow lines in between. In the marginal area is a row of tiny black dots. A brown spot is faintly visible in the grey spot near the trailing edge, and a black spot is on the edge of this grey spot. The Common Rose Bell is similar to the Triple-blotched Bell (Notocelia trimaculana), but is usually larger and has a broader forewing. In addition, the forewing is often paler in colour, and the spots at the leading edge are finer and more oblique. The wingspan is 15-20mm, and the flight period is in one generation from late May to August. Host plant: Hawthorn. Dutch name: Rozenhermelijnbladroller. Frisian name: –

Pine Shoot Moth – 2019 (NL)
(NCBI-index: 1.101046)
The Pine Shoot Moth (Rhyacionia buoliana) has an easily identifiable and striking appearance. This leafroller is very similar to the Orange-spotted Shoot (Rhyacionia pinicolana). Still, when you look closely at the irregular white line pattern, the Pine Shoot Moth shows an arc-shaped drawing at the end of the costa that does not continue to the centre. With the Orange-spotted Shoot, that white line continues to the apex. The forewing is otherwise bright orange, sometimes drenched with yellow-brown or reddish-brown. The flying period is from June to August in one generation, and the wingspan is 16-24mm. Larvae bore into the shoots. Host plant: Scots Pine. Dutch name: Gewone dennenlotboorder. Frisian name: –

Genus: Spilonota
Bud Moth – 2018 (NL)
(NCBI-index: 572898)
The Bud Moth (Spilonota ocellana) is a leafroller that is difficult to distinguish from the Larch-bud Moth (Spilonota laricana). A genitalia examination is needed, but it can be recognized because the Bud Moth has narrower forewings, is greyer, and has more black spots. The forewing of the Bud Moth is white, sometimes a pale yellow-brown with a grey diffuse colour. From the base, the forewings are black-brown up to a third and white for the rest. Usually, there is a black triangular mark near the apex. Lead grey spots can be seen from the apex to the dorsum. When resting, you can see a dark mark from above after those grey markings. The flying period in one generation is from May to September, and the wingspan is 12-17mm. The larvae feed on a wide range of shrubs and trees and, as the English name suggests, burrow into the buds during the spring, causing them to wither. Host plant: Oak, Apple, Hawthorn, and Sallow. Dutch name: Rode knopbladroller. Frisian name: –

Genus: Zeiraphera
Cock’s-head Bell – 2021 (NL)
(NCBI-index: 1.101070)
The Cock’s-head Bell (Zeiraphera isertana) is very similar to the Larch Tortrix (Zeiraphera griseana). The difference is in the light blotch halfway down the wing on the dorsum that extends towards the costa. With the Cock’s-head Bell, that spot never extends past the centre, whereas the spot on the Larch Tortrix goes past it. In addition, the Cock’s-head Bell is somewhat smaller and has shorter wings. The forewing is otherwise black or black-brown with white or grey markings. The flight period is one generation from May to September and the wingspan is about 17 mm. Host plant: Oak. Dutch name: Grootkopbladroller. Frisian name: –

Codling Moth – 2017 (NL)
(NCBI-index: 82600)
The Codling Moth (Cydia pomonella), also called Apple Leafroller, has a grey forewing with thin brownish transverse lines. On the outside, this leafroller has a coppery or gold-coloured eye with a triangular black stripe in the centre. The Codling Moth is responsible for the worm-eaten in apples and pears. That is why the apples on the fruit tree in my garden often have these weird spots. The flying time is sometimes two generations from May to October, and the wingspan is 14-22mm. The caterpillars feed on the fruits of apple, quince, pear, and other wild and cultivated fruits. Host plant: Apple and Pear. Dutch name: Fruitmot. Frisian name: –

Pea Moth – 2020 (NL)
(NCBI-index: 753170)
One species to be aware of to avoid confusing it with a species from another genus is the Pea Moth (Cydia nigricana). It is very similar to the Deep-brown Piercer (Grapholita tenebrosana). Both have a uniform forewing that is grey-brown to dark brown and sometimes yellow-grey. Near the costa, close to the apex, you see a few short white stripes alternating with black paces. The hindwing of the Pea Moth is dark brown with contrasting white fringes. The Deep-brown Piercer has a pale grey-brown hindwing, and the white stripes at the costa are less pronounced. The palps of the Pea Moth are mottled pale brown or dark grey on top and white on the underside. The Deep-brown Piercer they are entirely white. The flying period is from May to August in one generation, and the wingspan is 12-16mm. The larvae feed in the pods. Host plant: Pea. Dutch name: Erwtenbladroller. Frisian name: –

Sharp-winged Drill – 2019 (NL)
(NCBI-index: 1.869808)
A leafroller that, at first glance, has a bit of a grey appearance but, on closer inspection, still has a variety of stripes and colours. The Sharp-winged Drill (Dichrorampha acuminatana) has a forewing that is dark brown, sometimes with a light purple or pink glow. Furthermore, the wing is dotted with a faint yellow-brown, broad brown-white, almost triangular spot. There are three to six black dots on the termen, and the fringes are glossy dark grey with a central white band. The caterpillar feeds on the root of its host plant and is, therefore, not a leafroller in its name. The flying period is in two generations, from April to September, and the wingspan is 10-15mm. The larvae burrow into the rootstock and feed within. Host plant: Daisy. Dutch name: Margrietwortelmot. Frisian name: –

White-spot Yarrow Moth – 2024 (CH)
(NCBI-index: 1.211811)
With much effort and patience, it was finally possible to get a good picture of the White-spot Yarrow Moth (Dichrorampha ligulana). The base colour of the forewing is olive green to clay yellow. From the root tip, the number of dark-coloured spots becomes closer. Lead-grey shiny spots can be seen in the zoom field. Striking features are the black dots along the rear edge, the white spots along the front edge and the irregular white spot halfway along the wing that runs from the inner edge to halfway along the wing. The hindwings are plain brown. The flight period is from April to September, and the wingspan is 13-16 mm. Host plant: Wormwood and Yarrow. Dutch name: Witvlekwortelmot. Frisian name: –

In the summer, I often walk in a nature reserve after dinner. If you pay close attention, you will usually come across micro butterflies that emerge from their hiding place at dusk. A striking appearance is the poplar dwarf leafroller (Pammene populana) because of its large white spot on the otherwise predominantly dark brown forewing. The white spot at the inner edge is edged with a dark band. A pair of short cream-coloured bands can be seen along the leading edge.

Even though the drawing of the Sprout Marble (Celypha siderana) is quite striking, I still had to search hard to identify this leaf roller. Silver-grey spots spread over the forewing can especially be used as an essential characteristic. The forewing is also yellow-brown with many black narrow transverse lines and large black spots varying in size. The legs are ringed alternately yellow and brown. The flight period is one generation, from the beginning of June to the end of July, and the wingspan is 14-18mm. Host plant: Meadowsweet. Dutch name: Kristalbladroller. Frisian name: –

It is sometimes tough to distinguish certain types of leafrollers. At first, I was convinced that the spotted leafroller belonged to the Apotomis family. Still, after careful study and with the help of literature, I came to the Hedya species, Off-white Hedya (Hedya ochroleucana). This leafroller has a striking cream-coloured outer side of the forewing with a few light brown spots along the edge and a few small black dots in the pace itself. These light brown spots fade in colour over time, but this leafroller can still be recognized by the two dark stripes in the outer two spots. Two-thirds of the forewing is dark brown mixed with blue-grey and black surfaces. The flying period is from June to September in one generation, and the wingspan is 16-21mm. Larvae are spinning leaves together. Host plant: Rose and Apple. Dutch name: Grote witvlakbladroller. Frisian name: –

Marbled Orchard Tortrix – 2018 (NL)
(NCBI-index: 572853)
A leafroller that belongs to the white surface leafrollers is the ordinary Marbled Orchard Tortrix (Hedya nubiferana). The forewing is about 2/3 dark brown or dark yellow-brown mixed with blue-grey and black spots from the base. The other 1/3 towards the apex is white with pale grey or grey-brown streaks. The flying period in one generation is from May to August, and the wingspan is 15-21mm. Larvae feed on spun flowers, leaves, and shoots. Host plant: Oak, Hawthorn, and Blackthorn. Dutch name: Gewone witvlakbladroller. Frisian name: –

Arched Marble – 2018 (NL)
(NCBI-index: 1.109078)
A very striking appearance when you later enlarge the photos on your laptop is the Arched Marble (Olethreutes arcuella). The orange base colour of the wings with the silver-blue transverse lines is particularly striking when you encounter this leafroller in the field resting on a green leaf. Just after the front transverse band is a light yellow spot with black shading and some silver-blue spots. The orange colour can be seen as the colour of the dress of a Japanese geisha, and the silver-blue stripes are the spokes of the parasol that she spins. The Arched Marble flies in one generation from May to August, and the wingspan is 14-18mm. Host plant: Fallen leaves and plant remains. Dutch name: Geisha. Frisian name: –

Genus: Orthotaenia
Woodland Marble – 2020 (NL)
(NCBI-index: 1.594318)
The Woodland Marble (Orthotaenia undulana) is similar to the Common Marble (Celypha lacunana). The big difference is in the dark median band halfway up the forewing. With the Woodland Marble, this is an entirely dark band, but with the Common Marble, the pre-median cream-white band runs through the dark cross band in the middle, like a kind of finger. Furthermore, the apical zone of the Woodland Marble is lighter in colour, and the dark markings are more prominent. The larvae feed in leaves that are spun together. The flying period is one generation, from May to August, and the wingspan is 15-20mm. Host plant: Birch, Honeysuckle, and Billberry. Dutch name: Woudbladroller. Frisian name: –

Genus: Phiaris
Large Marble – 2023 (NL)
(NCBI-index: 1.594330)
Because of the clouds, staying in the heathland of a beautiful nature reserve was still pleasant, but as soon as the clouds disappeared, the temperature rose quickly. The disadvantage is that insects are also more active and cannot photograph easily. This also applies to the granite leaf roller (Phiaris schulziana), but with a lot of patience, I eventually succeeded. With its reddish-brown forewings with black speckles, thin white transverse bands, and small dots, this micromoth is almost unnoticeable. The flight period is in one generation from June to August, and the wingspan is 17-25mm. Host plant: Heather and Crowberry. Dutch name: Granietbladroller. Frisian name: –

Blueberry Tortrix – 2024 (CH)
(NCBI-index: 1.101140)
In the Netherlands, the Blueberry Tortrix (Phiaris bipunctana) is almost non-existent. It could be found on sandy soils in Gelderland and Overijssel. I have found this species in the Swiss Alps. The white forewing with sometimes somewhat yellowish irregular spots is black with grey spots at the wing root. The black runs diagonally from the leading edge across the wing inwards, bending towards the trailing edge to the inner edge corner. Halfway along the wing is a broad black transverse band with grey lead spots. The hind wings are dark grey but dull in colour. The flight period is from May to July, and the wingspan is 14-21 mm. Host plant: blueberry, red blueberry, rhododendron and wintergreen. Dutch name: Tweepuntige lijnbladroller. Frisian name: –

Tribe: Olethreutini
Genus: Piniphila
Pine Marble – 2019 (NL)
(NCBI-index: 1.101145)
The first spot of the Pine Marble (Piniphila bifasciana) was at night when it was attracted to light. This leafroller has a brown-grey forewing with two broad white cross bands. One band is 1/3 of the wing, and one is close to the apex. The bands are usually grey-white or yellow-brown and sometimes orange to pink—especially the band close to the wingtip. The flying period in one generation is from June to August, and the wingspan is 12-16mm. The larvae feed in a silken gallery among the young shoots and male flowers. Host plant: Scotch Pine. Dutch name: Tweebandbladroller. Frisian name: –
