Biology
Status: Scarce (Notable A)
Habitat: Broadleaved woodland (often glades & clearings), heathland, road verges.
Host plant: Hazel
Overwintering: Unknown location, but known to overwinter.
Food: Hazel leaves; adults and larvae make small holes.
Other notes: Widespread but scarce in southern England, one old record from Wales, absent from Scotland and Ireland. In England, one generation per year. New adults emerge July & August. Gravid females known in April & May. Eggs laid on the underside of hazel leaves. Larvae found from late April to July, and so likely to occur earlier than other Altica species; pupation in an earthen cell. Feeds on other tree species in continental Europe.
