Wasps are a diverse group, estimated at well over a hundred thousand described species around the world, and a great many more as yet undescribed. [9] [a] For example, almost every one of some 1000 species of tropical fig trees has its own specific fig wasp (Chalcidoidea) that has co-evolved with it and pollinates it. [10]
In all, perhaps 700,000 or so parasitoid wasp species are estimated to exist, but it’s probable that the number is far higher. Even the parasitoids are not immune to victimization.
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps being in the wasp-waisted Apocrita. As parasitoids , they lay their eggs on or in the bodies of other arthropods , sooner or later causing the death of these hosts .
The adults inject the eggs into a host, which they begin to consume after hatching. For example, the eggs of the endangered Papilio homerus are parasitized at a rate of 77%, mainly by Hymenoptera species. [23] Some species are even hyperparasitoid, with the host itself being another parasitoid insect. Habits intermediate between those of the ...
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]
They tend to be less conspicuous than the social (wasps) do,” Kimsey said, adding that they are “good to have around” to eat other bugs such as caterpillars. There are roughly 300 species of ...
Insects often adapt their nests to reduce parasitism. For example, one of the key reasons why the wasp Polistes canadensis nests across multiple combs, rather than building a single comb like much of the rest of its genus, is to avoid infestation by tineid moths. The tineid moth lays its eggs within the wasps' nests and then these eggs hatch ...
