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.
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.
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.
Phymata pennsylvanica, known generally as the Pennsylvania ambush bug or Pennsylvania jagged ambush bug, is a species of ambush bug in the family Reduviidae. It is found in North America. It is found in North America.
The pair attached to the second segment are called secondary antennae or simply antennae. 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 physical variation of antennae is important for the identification of many beetle groups. The Curculionidae have elbowed or geniculate antennae. Feather like flabellate antennae are a restricted form found in the Rhipiceridae and a few other families. The Silphidae have a capitate antennae with a spherical head at the tip.
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 ...
