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.

The number of segments in an antenna varies amongst insects, with higher flies having 3-6 segments, [21] while adult cockroaches can have over 140. [22] The general shape of the antennae is also quite variable, but the first segment (the one attached to the head) is always called the scape, and the second segment is called the pedicel.
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.
The second antennae are plesiomorphically biramous, but many species later evolved uniramous pairs. [2] The second antennae may be significantly reduced (e.g. remipedes) or apparently absent (e.g. barnacles). The subdivisions of crustacean antennae have many names, including flagellomeres (a shared term with insects), annuli, articles, and ...
