Arenocoris fallenii Fallén's Leatherbug
Family: Coreidae

Although variable in colour, this squashbug has two rows of pale spines on the pronotum which form a distinctive backwards pointing V-shape. The 3rd antennal segment is  parallel-sided. See the much rarer A. waltlii.

Adults overwinter and nymphs can be found June-July feeding on Common Storksbill Erodium cicutarium. Probably double-brooded when conditions are favourable.

Mainly local in coastal sand dunes between Norfolk and south Wales; also in the East Anglian brecks and increasingly inland in recent years, in gravel pits and sandy habitats.

Adult: All year
Length 6-7 mm
