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.
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder.
Emergence dates and speed of the life cycle vary across the wasp's broad distribution. In Ontario, the flight season typically begins the last week of June and continues until early September. Emergence dates and duration of flight season can be influenced by droughts, which could postpone emergence or shorten the flight season.
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 ...
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.
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 ...
Apocrita (wasps, bees and ants) Hymenoptera is a large order of insects , comprising the sawflies , wasps , bees , and ants . Over 150,000 living species of Hymenoptera have been described, [ 2 ] [ 3 ] in addition to over 2,000 extinct ones. [ 4 ]
