Caloptilia rufipennella (Hübner, 1796)
[Lepidoptera: Gracillariidae]

Small Red Slender


Tinea rufipennella Hübner, 1796. Samml. Europ. Schmett.: fig. 204
Caloptilia rufipennella
(Hübner, 1796).


Leaf miner: The mine begins as an inconspicuous, lower-surface, epidermal corridor. This widens into a smallish triangular blotch, usually in the axil of a vein; the mine is fairly transparant. Older larvae live free, in in a lobe of the leaf that has been forced downwards and rolled into a cone. In the course of its development the larva makes three (rarely two) of such cones, ascending in size, on the same leaf or not; the first is no more than a downfolded leaf margin. Pupation in a membranaceous, yellowish cocoon at the underside of a leaf (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).

Greenish, head lighter (Bladmineerders van Europa).

Larva initially in a small mine, but later folding the leaf and feeding within (UKMoths).

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

See Patocka and Zach (1995a) or Patocka and Turcáni (2005a) for a description (Bladmineerders van Europa).

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

Time of year - larvae: June-July (British leafminers).

Time of year - adults: The moths emerge in August and overwinter, reappearing in the following spring (UKMoths).

Distribution in Great Britain & Ireland: The species was only discovered in Britain in 1970, and had a scattered northern and eastern distribution, but is now expanding its range and is fairly common in much of England, including Bedford (Studham) and Scotland (UKMoths); Ayrshire (VC74), Banffshire (VC94), Bedfordshire (VC30), Breconshire (VC42), Cambridgeshire (VC29), Cumberland (VC70), Denbighshire (VC50), Derbyshire (VC57), East Cornwall (VC2), East Norfolk (VC27), East Ross (VC106), East Suffolk (VC25), East Sutherland (VC107), Easterness (VC96), Elgin, Glamorganshire (VC41), Herefordshire (VC36), Hertfordshire (VC20), Isle of Wight (VC10), Kincardineshire (VC91), Middlesex (VC21), Monmouthshire (VC35), North Aberdeenshire (VC93), North Essex (VC19), North Hampshire (VC12), North Somerset (VC6), North Wiltshire (VC7), South Northumberland (VC67), Shropshire (VC40), South Aberdeenshire (VC92), South Devon (VC3), South Hampshire (VC11), South Lancashire (VC59), South Wiltshire (VC8), Staffordshire (VC39), Surrey (VC17), Warwickshire (VC38), West Gloucestershire (VC34), West Kent (VC16), West Norfolk (VC28), West Suffolk (VC26), Westmorland (VC69) and Worcestershire (VC37) (NBN Gateway).
