The basic color of the upperside of the body is orange yellow, with wide black longitudinal stripes. The pronotum has six black bands. The antennae are black. Also the sides of the abdominal segments (connexivum) are yellow with many small black spots. The legs are mostly orange, which distinguishes it from its relative, G. italicum.
[1]: 22–48 Although the general function of the three body regions is the same across all insect species, there are major differences in basic structure, with wings, legs, antennae, and mouthparts being variable from group to group.
Berytidae is a family of the order Hemiptera ("true bugs"), commonly called stilt bugs [2] or thread bugs [3] (not to be confused with the thread-legged bugs, Emesinae).Most berytids are brown to yellow, with species that are plant sap feeders, a few being predaceous.
The body has a few short, whitish bristles and the antennae and limbs are pale brown. Distinguishing this ant from other members of its genus, Paratrechina, is easy because its antennae and legs are so long. The first segment of each antenna is more than twice as long as the length between its base and the back edge of the head.
The basic color of the upperside of the body is red, with wide black longitudinal stripes. The pronotum has six black bands. The antennae are black. Also the sides of the abdominal segments (connexivum) are red with many small black spots. The legs are mostly black, which distinguishes it from its relative, G. lineatum.
Most black flies gain nourishment by feeding on the blood of mammals, including humans, although the males feed mainly on nectar. They are usually small, black or gray, with short legs and antennae. They are a common nuisance for humans, and many U.S. states have programs to suppress the black fly population.
Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the prothorax. [2]
The Nematocera (the name meaning "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae.This group is paraphyletic and contains all flies except for species from suborder Brachycera [4] (the name meaning "short-horns"), which includes more commonly known species such as the housefly or the common fruit fly.
