Phymata americana show sexual dimorphism in size and color pattern. [ 9 ] [ 11 ] [ 13 ] [ 14 ] [ 15 ] Males tend to be darker than females, although only as adults. [ 13 ] Additionally, the degree of coloration is condition dependent , with increased food availability resulting in darker males and females. [ 13 ]
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.
Phymata is a genus of assassin bugs belonging to the family Reduviidae, subfamily Phymatinae, [1] commonly called jagged ambush bugs. They can be a variety of colors, with their coloring helping them camouflage with the plants they live on.
Adults of Phymata crassipes can reach a length of about 7–9 mm. The body appear ornamented with some extrusions. Their triangular scutellum is shorter than a pronotum without prominent tubercles. They possess functional wings. They have clubbed antennae and enlarged fore femora and abdomen.
Antennae vary greatly in form, sometimes between the sexes, but are often similar within any given family. Antennae may be clubbed, threadlike, angled, shaped like a string of beads, comb-like (either on one side or both, bipectinate), or toothed. The physical variation of antennae is important for the identification of many beetle groups.
Moth antennae are usually feathery with no ball on the end. The divisions are named by this principle: "club-antennae" (Rhopalocera) or "varied-antennae" (Heterocera). Lepidoptera first evolved during the Carboniferous period, but only evolved their characteristic proboscis alongside the rise of angiosperms in the Cretaceous period. [4]

Histeridae is a family of beetles commonly known as clown beetles or hister beetles.This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends.
