Sphex pensylvanicus is a large, black wasp, significantly larger than their congener Sphex ichneumoneus (the great golden digger wasp). [6] Males are smaller than females, at only 19–28 mm (0.7–1.1 in) long compared with typical female sizes of 25–34 mm (1.0–1.3 in). [2]
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 ...
Approximately 300 species of Polistes paper wasps have been identified worldwide. The most common paper wasp in Europe is Polistes dominula. [2] The Old World tribe Ropalidiini contains another 300 species, and the Neotropical tribes Epiponini and Mischocyttarini each contain over 250 more, so the total number of true paper wasps worldwide is about 1100 species, almost half of which can be ...
P. exclamans have antennae banded with red, black and yellow, while most paper wasps only have one antennae color. In females, the fore wing length can range from 13.0 to 16.5 mm (0.51–0.65 in) and in males the fore wings can range from 12.0 to 15.0 mm (0.47–0.59 in). [ 8 ]
Some caterpillars even bite the female wasps that approach them. Some insects secrete poisonous compounds that kill or drive away the parasitoid. Ants that are in a symbiotic relationship with caterpillars, aphids or scale insects may protect them from attack by wasps. [18] [19] Parasitoid wasps are vulnerable to hyperparasitoid wasps.
Also, a related genus of Asian nocturnal vespines, Provespa, is referred to as "night wasps" or "night hornets", [5] though they are not true hornets. [6] Some other large wasps are sometimes referred to as hornets, most notably the bald-faced hornet (Dolichovespula maculata) found in North America. It is set apart by its black and ivory ...
The European paper wasp (Polistes dominula) is one of the most common and well-known species of social wasps in the genus Polistes.Its diet is more diverse than those of most Polistes species—many genera of insects versus mainly caterpillars in other Polistes—giving it superior survivability compared to other wasp species during a shortage of resources.
Priocnemis monachus is a species of spider wasp endemic to New Zealand, where it is known as the black hunting wasp or ngaro wīwī. It hunts large tunnelweb or trapdoor spiders, paralysing them with its sting and storing them in burrows for its larvae to eat alive.
