Some wasps are even parasitoids of parasitoids; the eggs of Euceros are laid beside lepidopteran larvae and the wasp larvae feed temporarily on their haemolymph, but if a parasitoid emerges from the host, the hyperparasites continue their life cycle inside the parasitoid. [19] Parasitoids maintain their extreme diversity through narrow specialism.
Andricus quercuscalicis (Burgsdorf, 1783) (Hymenoptera: Cynipidae) [7] is a small gall wasp with an obligate two-phase life-cycle that requires both pedunculate oak (Q. robur L.) (or occasionally sessile oak Q.petraea L.) [3] and Turkey oak (Quercus cerris L.). Therefore, as with most oak gall wasps, this species has alternate sexual and ...
Palaeovespa florissantia, late Eocene. The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as Polistes fuscatus, Vespa orientalis, and Vespula germanica) and many solitary wasps. [1]
Chrysis ignita and its family of chrysidid wasps have evolved effective defenses for their risky life cycle. While the life of a cuckoo wasp may seem easy, it must drop off its young to be raised by a host wasp species. The ruby-tailed wasp has to infiltrate a nest full of defensive mother wasps, often armed with powerful stingers and jaws.
Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
The first stage of the insect life cycle is the egg, or embryo, for all developmental strategies. The egg begins as a single cell which divides and develops into the larval form before hatching. Some insects reproduce by parthenogenesis or may be haplodiploid, and produce viable eggs without fertilization. The egg stage in most insects is very ...
However, the term ichneumon wasps can refer specifically to the genus Ichneumon within the Ichneumonidae and thus can cause confusion. A group of ichneumonid specialists have proposed Darwin wasps as a better vernacular name for the family. [ 5 ]
Cynips quercusfolii, also known as the cherry gall wasp, is a gall wasp species in the genus Cynips and family Cynipidae. The species is important for the production of commercial nutgall formed on Quercus lusitanica (the gall oak). Galls are located on the underside of leaves, with the majority of galls being on the second and third veins from ...
