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.
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 ...
Species of Sphaerosoma are very small, around 1 to 2 mm in length rounded beetles with clubbed antennae. They are fungivores, having been observed feeding on mushrooms, and have also been found in leaf litter and on decaying bark.
Large antennae on a longhorn beetle. Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
The antennae always have two grooves on the underside; the club is variable in shape. Throughout the family, the front pair of legs in the male, and with three exceptions ( Libythea , Pseudergolis , and Calinaga ) in the female also, is reduced in size and functionally impotent; in some, the atrophy of the forelegs is considerable, e.g., the ...
