However, the majority of wasp species are solitary, with each adult female living and breeding independently. Females typically have an ovipositor for laying eggs in or near a food source for the larvae, though in the Aculeata the ovipositor is often modified instead into a sting used for defense or prey capture. Wasps play many ecological roles.
So, all female offspring inherit the male's chromosomes 100% intact. As long as a female has mated with only one male, all her daughters share a complete set of chromosomes from that male. In Hymenoptera, the males generally produce enough sperm to last the female for her whole lifetime after a single mating event with that male. [20]
Winged female and wingless male. Blastophaga psenes is a wasp species in the genus Blastophaga. It pollinates the common fig Ficus carica and the closely related Ficus palmata. [3] These wasps breed in figs without the need for a colony or nest, and the adults live for only a few days or weeks. [4]
After mating, the female wasp seeks out a tarantula, either free-ranging or in its burrow. After grappling with the tarantula, the wasp delivers a powerful sting that paralyzes the tarantula, but keeps it alive. [2] This allows the wasp to lay an egg that adheres to the spider's abdomen. One egg is provisioned per tarantula.
Ammophila urnaria feeds on nectar and can often be seen on the flower heads of sorrel or onion. [2] The breeding season is in summer. The female wasp digs a succession of burrows in sandy soil, provisioning each burrow with one or more paralysed caterpillars, lays an egg on the first caterpillar in each and seals the hole.
After mating, female wasps will select a site and begin digging a burrow, normally under sidewalks, roadsides and embankments. They often choose lawns in populated areas, said the Smithsonian ...
Egg laying by subordinate females and the oophagy of these eggs by dominant female wasps will occur until two weeks after the first female eggs emerge. [10] Prior to these two weeks, egg layers will continuously eat other female wasps’ eggs approximately eleven minutes post being laid; however, no egg layers would ever eat their own eggs ...
As in other Nasonia wasps, N. vitripennis is haplodiploid, having haploid males and diploid females, and measures from 2–3 mm in length, with larger and darker-colored females than males. These wasps, like most other insects, show much sexual dimorphism, and females tend to be less easy to distinguish by species than males.
