Male false oil beetle Oedemera nobilis, copyright Entomart.

Belongs within: Tenebrionoidea.

The Oedemeridae are a group of elongate, soft-bodied beetles whose larvae feed on dead wood. Adults may feed on pollen or be short-lived and not feed at all. Members of this family are commonly known as false blister beetles due to their resemblance to the blister beetles of the Meloidae, which they also resemble in producing irritant chemicals for defense that may cause blisters on the skin of humans (Bouchard 2014).

Characters (from Lawrence & Britton 1991): Elongate, parallel-sided, soft-bodied, often bicoloured and clothed with short, decumbent hairs. Head usually somewhat produced anteriorly; antennal insertions located dorsally in front of eyes, antenna 11-segmented, filiform, serrate or incrassate; apical segment of maxillary palp more or less expanded and truncate (excavate in some males); lateral pronotal carinae absent; fore coxae projecting, trochantins exposed, fore coxal cavities externally open, internally closed; mesocoxal cavities contiguous, laterally open; tarsal formula 5-5-4, penultimate tarsal segment lobed beneath; abdomen with five or six ventrites, two ventrites connate. Larvae elongate, subcylindrical, very lightly sclerotised, with large, often slightly asymmetrical head and asperity-bearing ampullae on T1–T2 or T1–T3 and S2–S4 or S3–S4. Antennae well developed; epicranial stem long, frontal arms V-shaped; mandibles large and asymmetrical, with transversely ridged molae; ligula well developed, with prehypopharyngeal lobe between it and hypopharynx.
