Coleophora glaucicolella Wood, 1892
[Lepidoptera: Coleophoridae]

Grey Rush Case-bearer

Coleophora glaucicolella Wood, 1892. Ent. mon. Mag.: 102.

Leaf-miner and case-bearer: The full grown larval case is very similar to that of C. alticolella, but the larvae can be differentiated (UKMoths).

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 UKMoths.

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

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

Hosts in Great Britain & Ireland:

Juncus       UKMoths

Hosts elsewhere: Currently unknown.

Time of year - larvae: Currently unknown.

Time of year - adults: June to August at sunrise, dusk and night.

Distribution in Great Britain & Ireland: Widespread and common in Britain (UKMoths); including Anglesey (VC52), Bedfordshire (VC30), Caernarvonshire (VC49), Cambridgeshire (VC29), Cardiganshire (VC46), Carmarthenshire (VC44), Cheshire (VC58), Denbighshire (VC50), East Kent (VC15), East Ross (VC106), East Suffolk (VC25), East Sussex (VC14), Flintshire (VC51), Glamorganshire (VC41), Huntingdonshire (VC31), Merionethshire (VC48), Mid-west Yorkshire (VC64), Middlesex (VC21), North Essex (VC19), North Hampshire (VC12), North Somerset (VC6), North Wiltshire (VC7), Shropshire (VC40), South Aberdeenshire (VC92), South Hampshire (VC11), South Lancashire (VC59), South Wiltshire (VC8), Staffordshire (VC39), Surrey (VC17), Warwickshire (VC38), West Cornwall (VC1), West Lancashire (VC60), West Norfolk (VC28), West Suffolk (VC26), Westmorland (VC69) and Worcestershire (VC37) (NBN Gateway).

It is often abundant on salt marshes. Sometimes goes unrecorded because of confusion with another Juncus feeding species, C. alticolella (UKMoths).

Also recorded in the Republic of Ireland and Northern Ireland (Karsholt and van Nieukerken in Fauna Europaea). See also Ireland's NBDC interactive map.
