Callirhytis seminator, the wool sower, is a species of gall wasp in the family Cynipidae. [1] The adult wasps are about 1/8" in length and dark brown in color. The larvae are white and fat and have no legs. The wasps only lay eggs on white oak trees and only in the spring. They lay the egg in a gall, a round, white structure resembling a cotton ...
The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
Often multiple wasps in different life stages occupy the same gall. The induced galls help establish complex insect communities, promoting the diversification in niche differentiation. Furthermore, the adaptive value of these galls could be attributed their ecological benefits such as nutrition, provision of microenvironment, and enemy avoidance.
Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
Cynipini is a tribe of gall wasps. These insects induce galls in plants of the beech and oak family, Fagaceae. [1] They are known commonly as the oak gall wasps. [2] It is the largest cynipid tribe, with about 936 [3] to 1000 [2] recognized species, most of which are associated with oaks. [2] The tribe is mainly native to the Holarctic. [3]
Cicadas are paralyzed by the wasp's sting and will be carried back to the burrow, said the Smithsonian. The cicadas will normally be captured in flight. Do killer cicada wasps sting?
