Among the social wasps, Stenogastrinae are known as hover wasps due to their distinctive hovering flight. [31] Males often hover to display banding patterns on their abdomen as a territorial display. [32] [33] Among the solitary wasps, parasitoid species such as scoliid wasps exhibit hovering behaviour while hunting for prey to feed their larvae.
The tip speed (u) is about 1 m/s (3.3 ft/s), and the corresponding Reynolds number about 103. At the smaller end, a typical chalcidoid wasp has a wing length of about 0.5–0.7 mm (0.020–0.028 in) and beats its wing at about 400 Hz. Its Reynolds number is about 25.
Wasps come in a variety of colors — from yellow and black to red and blue — and are split into two primary groups: social and solitary. Most wasps are solitary, non-stinging insects that do ...
Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
Dolichovespula maculata is a species of wasp in the genus Dolichovespula and a member of the eusocial, cosmopolitan family Vespidae.It is taxonomically an aerial yellowjacket but is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and ...
Other wasps victimize cicadas, crickets, katydids, spiders, stinkbugs, walkingsticks, water striders and probably every other arthropod group. In all, perhaps 700,000 or so parasitoid wasp species ...
The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
