Coleophora lutipennella (Zeller, 1838)
[Lepidoptera: Coleophoridae]

Common Oak Case-bearer



Ornix lutipennella
Zeller, 1838. Isis: 713.
Coleophora lutipennella
(Zeller, 1838).


Leaf-miner and case-bearer: The larvae of this species feed on oak, forming a pear-shaped silken case, initially on the underside of a leaf, moving its case to an angle of twigs to over-winter (UKMoths). First case formed of silk, larva mining leaves. Feeding in spring in a new case on catkins and also mining leaves. Very similar to case of C. flavipennella (British leafminers).

Light brown, trivalved, tubular silken case of c. 7 mm; mouth angle c. 45°. Immediately after eclosion the larva begins the construction of its case, that entirely consists of silk (Bladmineerders van Europa).

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

The larva is illustrated in Bladmineerders van Europa.

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Distinguishing between the final cases of Coleophora flavipennella and Coleophora lutipennella on Oak (Quercus) is not possible but progress was made by Brian Goodey with their winter cases (Goodey, B., 1992. Ent. Rec. 104: p169-171). His findings were that the winter cases of these two Coleophora spp. could be distinguished by examining the anal end of the case. Coleophora flavipennella has a patch of leaf tissue incorporated into the case, seen as a raised area, whereas in Coleophora lutipennella this raised area does not exist (British leafminers Newsletter).

Adult: The adult is illustrated in UKMoths by Rob Edmunds. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Time of year - larvae: Late September to late October, then April to early June (British leafminers).

Time of year - adults: The adult moths emerge in a single generation in July and August, and are attracted to light, often flying some distance from the host plant (UKMoths).

Distribution in Great Britain & Ireland: The moth is thought to be common in England, Wales and southern Scotland (UKMoths) including Bedfordshire, Breconshire, Caernarvonshire, Cambridgeshire, Cardiganshire, Cheshire, Denbighshire, Derbyshire, East Cornwall, East Kent, East Suffolk, Flintshire, Glamorgan, Herefordshire, Hertfordshire, Huntingdonshire, Merionethshire, Middlesex, North Essex, North Hampshire, North Somerset, North Wiltshire, Shropshire, South Hampshire, South Lancaster, South Wiltshire, Stafford, Surrey, Warwickshire, West Kent, West Lancaster, West Norfolk, West Suffolk, Westmorland and Worcestershire (NBN Atlas).

Also recorded in the Republic of Ireland (Karsholt and van Nieukerken in Fauna Europaea).

Distribution elsewhere: Widespread in continental Europe including Albania, Austria, Belgium, Bulgaria, Croatia, Czech Republic, Danish mainland, Estonia, Finland, French mainland, Germany, Greek mainland, Hungary, Italian mainland, Latvia, Lithuania, Macedonia, Norwegian mainland, Poland, Portuguese mainland, Romania, Russia - Central, Slovakia, Slovenia, Spanish mainland, Sweden, Switzerland and The Netherlands. Also recorded in Near East (Karsholt and van Nieukerken in Fauna Europaea).
