Marsh Click Beetle - Actenicerus sjaelandicus


    Size 10 to 16mm. A large species, varying in shade from rather grey-brown to chestnut-brown. A fairly dense covering of lighter grey coloured hairs gives the pronotum and elytra a patterned appearance and strong ridges running down the length of the elytra are visible. The legs and antennae are unicolourous with the rest of the insect. The antennae are around the length of the head and pronotum or slightly longer.
