A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas.Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it into a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host.
A female S. speciosus digging a burrow next to a driveway Eastern cicada-killer wasp holding a paralyzed cicada at John Heinz National Wildlife Refuge. Solitary wasps like the eastern cicada killer are very different in their behavior from the social wasps such as hornets, yellowjackets, or paper wasps. Cicada killer females use their stings to ...
Abe 2] While a single wasp cannot inject a lethal dose, multiple stings can be lethal even to people who are not allergic if the dose is sufficient, and allergy to the venom greatly increases the risk of death. Tests involving mice found that the venom falls short of being the most lethal of all wasp venoms, having an LD 50 of 4.0 mg/kg.
Conservationists have introduced a wasp to tackle an invasive scale insect destroying forest habitat of the critically-endangered Wilkins’ bunting. Remote island bird at risk of extinction is ...
Pompilidae, Tachypompilus ignitus, a typical spider-hunting wasp, has paralysed a female Huntsman spider, and is dragging it up a wall to the intended shelter Sphecidae, Ammophilinae, Eremnophila aureonotata transporting a paralysed prominent caterpillar to the nest she has excavated Katydid paralysed by a Sphecid wasp, and left outside the tunnel while the wasp performs a final inspection of ...
The Wilkins’ Bunting birds, a rare species living on the Nightingale Island in the South Atlantic, won’t go extinct anytime soon — thanks to wasps.
Cicada killer wasps (genus Sphecius) are large, solitary, ground-dwelling, predatory wasps. They are so named because they hunt cicadas and provision their nests with them, after stinging and paralyzing them. Twenty-one species worldwide are recognized. The highest diversity occurs in the region between North Africa and Central Asia.
Unlike true parasites, the wasp larvae eventually kill their hosts. Solitary wasps parasitize almost every pest insect, making wasps valuable in horticulture for biological pest control of species such as whitefly in tomatoes and other crops. Wasps first appeared in the fossil record in the Jurassic, and diversified into many surviving ...
