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 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. The remaining antennal segments or flagellomeres are called the flagellum. [17]: 8–11 General insect antenna types are shown below:
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. As for ...
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.
