Chrysomelid beetle, Labidostomis humeralis

Labidostomis humeralis. Small leaf beetle fond on tall grasses. Dark metallic head and pronotum. Pronotum deeply punctured. Iridescent black-green. Elytra dark brown with a single small black spot on each shoulder. Black antennae serrated. Single small brown segment at base. Clings to grass grain. Labidstomis male usually larger than female. Front pair of legs are longer and thicker than the other two pairs. On males size difference of front legs is pronounced with much thicker femora like back leg of a grasshopper. Male pronotum is slightly separated from elytra, but on female it is tightly close similar to other Chrysomela and Clytra spp. The beetle springs when distrubed rather than flies. 7.5-10mm male. 0605vsen7C19_06_18AsR.jpg Vsenory, Czech Republic Canon 7D EFS 60 2.8 1/320 f/3.6 iso 250
