Wireworm Click Beetle - Agriotes obscurus
Size 7 to 10 mm. This is a mid to dark brown coloured click beetle, with ridged lines running down the elytra which also has yellowish hairs. Note that A. lineatus may look similar, but the stripes along the elytra in that species have a two-tone dark and light appearance. Agriotes sputator is another similar species, but the pronotum, in A. obscurus is much narrower at the front than in the middle and much more strongly contracted towards the front. Conversely, in A. sputator, the pronotum is more nearly parallel-sided and much less strongly contracted to the front.
Favouring meadows and grassy places.
Adults March to June
Adults move at night, feeding on the leaves of grasses. They lay eggs into the surface soil in April, May and early June. Young larvae hatch in June or July. These larvae, called Wireworms, are long lived (up to four years in this stage of development) and feed on the roots of grasses and other plants.
Fairly frequent and widespread in Britain
