|A BIT ABOUT BUGS
Both species in this primitive genus are characterised by strongly convex and coarsely punctured forewings. They are flightless and the hind legs are not modified for jumping.
U. trivia males are distinctively marked with a pale yellowish base colour and dark streaks on the forewing through the clavus, and weakly along the cubital vein and radial veins. There are also dark marks on the vertex, close to the eye. Females are entirely yellowish-brown with slight dark mottling.
A scarce species primarily found in southern England on chalk downland or coastal sites, unlike the common U. reticulata. Foodplant assocations are unclear, but probably include Horseshoe Vetch Hippocrepis comosa.
