Sphaeroderma testaceum

3.5-4.0mm.(Joy), 2.5-4.5mm (Bienkowsky). Broad oval and entirely testaceous. Head shiny with very fine puncturation, just visible at X20. Eyes prominent and touching pronotum in normal setting. Frontal tubercles deeply bordered. Antennae separated by about the length of the first segment, filiform with all segments elongate, terminal segment angled on outer side. Pronotum densely punctured, coarsely so towards base becoming finer anteriorly. Adults occur only occasionally during April and May and in our experience they do not become common until June and July and then remain so until September or October. The species normally overwinter as third instar larvae but also sometimes as adults among grass tussocks. Pupation occurs in the spring and new generation adults from May. Both larvae and adults feed on leaves.
