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.
