The legs are similar in colour to the elytra. The antennae are slightly shorter than the length of the head and pronotum. common. emerging in May or June  can be found resting on flowers of various species (particularly Umbellifers) This species  is considered a pest.

 

Athous bicolor Size – 8-10mm. an elongated species. The elytra are an ochre/yellow colour with obvious ridges and pits running down their length. The pronotum is slightly darker. The hairs are very similar in colour to the elytra.

Agriotes pallidulus Size – 4-6mm.  A small Agriotes. The elytra are yellow/orange – dark orange in colour, with lighter specimens showing a darker orange stripe down the centre. Rows of pits are distinct running the length of the elytra. The pronotum and head are a darker brown, sometimes with orange angles on the pronotum. There is a noticeable covering of slightly lighter hairs. The legs and antennae are yellow/orange and the antennae are long, extending beyond the posterior edge of the pronotum

 

Ctenicera cuprea Size – 11-16mm. A large, very elongated species and variable species. Colour combinations include dark yellow elytra with green tips and a green pronotum, wholly green or wholly purple. There is a conspicuous dipped line down the centre of the pronotum and the elytra are ridged. Most specimens have a very metallic appearence. Males have very long and pectinate antennae, whilst females have shorter and plainer, but noticeably segmented antennae. The legs are black. common

 

Agriotes obscurus Size – 7-10mm.  Very similar to A. lineatus. A uniform mid-brown coloured species with a very dense covering of lighter brown/cream hairs. The pronotum and elytra appear rounded. Rows of pits form ridges down the length of the elytra that appear in ‘pairs’ and are a darker brown colour to the rest of the elytra. The legs and antennae are slightly darker brown than the rest of the insect. The antennae are slightly longer than the length of the head and pronotum

 

Sericus brunneus? Description – Male with dark brown head and pronotum and lighter mid-brown elytra. Female with dark brown head and lighter brown pronotum, patterened with a darker brown central spot running the length of the pronotum and two dark areas at the edges starting half way down and extending to the base of the posterior angles. The elytra are a uniform light brown. Longitudinal rows are visible running the length of the elytra and the pronotum is densely pitted on close examination. The legs are uniform light brown. Antennae are dark brown and extend to the posterior margin of the pronotum in the male, shorter in the female.

 

 

Agriotes sputator Size – 6-9mm.  Uniformly dark brown over the head, pronotum and elytra with a dense covering of light brown hairs. Ridges running the length of the elytra are obvious. The legs and antennae are a more chestnut/red brown colour. The antennae are short, not extending beyond the end of the pronotum.
