Alebra coryli

Length 3.5 to 4.0 mm, associated with hazel. The Alebra genus is distinguished from all other Typholocybinae by the forewing appendix - a narrow zone at the forewing apex which is not crossed by any veins.  Individuals vary in colour and intensity of markings, and males and females differ.   The hind tibia have light to slightly dark spots.

Females have 2 well-defined orange or yellow longitudinal stripes over a pale forewing.  Males have vertex, head, forewing and pronotum yellow or orange.

There are several similar Alebra, and identification is difficult. If in doubt, the male sternal apodemes should be examined - these are internal abdominal structures assocated wth the song apparatus.

Detailed examination of the specimen is needed to identify this species.  Photograph underside as well as dorsal side, and ensure photographs show hind tibia clearly.  Ensure you have identified the host plant.  It is helpful to confirm whether male or female. See Biedermann & Niedringhaus for illustrations of sternal apodemes, and Le Quesne for guidance on how to examine them.

Feeds mostly on Hazel. 

Summer-Autumn.
