Dacne rufifrons

It has dark blackish or blue-black elytra with indistinct red blotches. Associated with bracket fungi and decaying timber. Breeds in dry fungus and decaying timber of broad-leaved trees. Widespread and fairly frequent in England and Wales, less commo

Languria marginipennis

Identification: "green-blue or blue" (Schwarz, 1878a) Both Schwarz (1878a, p. 357) and Schaeffer (1904, p. 200) say the thorax has a median dark spot, but, although the majority of specimens examined have it, some do not, or it is so faint as not to

Clover Stem Borer

Triplax festiva

Identification: color pattern unique among our erotylids

Triplax frosti

infrequently collected, perhaps due to the cryptic nature of the host fungus

Triplax marcescens

Identification: Dulled elytra, from Arizona (Paul Skelley, 12 August, 2013) "...elytra entirely dull, contrasting rather strongly with the nitidous pronotum." Another 'rare' erotylid form southern Arizona. I'm sure these are all more common, we just
