Western Conifer Seed Bug - Leptoglossus occidentalis
Length ~20 mm. A very large and spectacular squashbug which has characteristic expansions on the hind tibiae and a white zig-zag mark across the centre of the forewings.
Preferring areas with Pine trees.
Adult: All year.
The bug feeds on Pines and seems very likely to become established here; nymphs have so far been found at one location. It is attracted to light and may enter buildings in search of hibernation sites in the autumn.
Native to the USA and introduced into Europe in 1999, this species has since spread rapidly and during the autumn of 2008 and 2009 influxes of immigrants were reported from the coast of southern England, with a wide scatter of records inland.
Increasing in frequency in Leicestershire and Rutland.
