In Phymata, the scutellum is triangular and shorter than the pronotum. In Macrocephalus, the scutellum is narrow and rounded, extending to the tip of the abdomen. [2] Phymatinae normally have a large fore femur and clubbed antennae. The forewing membranes sometimes lack distinct cells. [3] The antennae have four segments. There are two ocelli.

How to Identify Them: Carpet beetles have oval-shaped bodies with a hard shell and short, clubbed antennae. They are generally 2.5 millimeters in size, but their color varies by species.
The antenna surface is covered with large numbers of olfactory scales, hairs, or pits; as many as 1,370,000 are found on the antennae of a monarch. Antennae are extremely sensitive; the feathered antennae of male moths from the Saturniidae, Lasiocampidae, and many other families are so sensitive that they can detect the pheromones of female ...

Legend: a, antennae; c, compound eye; lb, labium; lr, labrum; md, mandibles; mx, maxillae; hp hypopharynx.
Most butterflies have thin slender filamentous antennae which are club shaped at the end. Moths, on the other hand, often have comb-like or feathery antennae, or filamentous and unclubbed. [ 2 ] [ 3 ] This distinction is the basis for the earliest taxonomic divisions in the Lepidoptera: the Rhopalocera ("clubbed horn", the butterflies) and the ...
Clubbed thumbs or “toe thumbs,” officially named brachydactyly type D, are caused by a genetic mutation and they feature end bones that are shorter than usual and much wider-than-normal nails.
