Recorded widely but sparsely throughout Britain, although Scottish records are so far only from the west of the country. Observations appear to have declined in recent years (Musgrove, 2023).
Aneugmenus temporalis is black bodied in both sexes, though the pronotum may be edged narrowly with white. The occipital carina does not extend more than half way up the eye. The distance between cenchri is less than the width of a cenchrus, the cenchri themselves being elongate (3:1). In males the hind femora are black.
Larvae feed on bracken. They are green in colour and all larvae in the Aneugmenus genus have a v-notch in the first thoracic annulet behind the head.
