In some species, the larvae are predatory themselves; the wasp eggs are deposited in clusters of eggs laid by other insects, and these are then consumed by the developing wasp larvae. [10] The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length. [11]
The wasps, bees, and ants together make up the suborder (and clade) Apocrita, characterized by a constriction between the first and second abdominal segments called a wasp-waist , also involving the fusion of the first abdominal segment to the thorax. Also, the larvae of all Apocrita lack legs, prolegs, or ocelli.
This particular diagram is close in likeness to that of a yellowjacket wasp found commonly around the world. It can be identified as female by both the number of division on its antenna and by the presense of its sting. Reasons for nominating; I am self nominating my latest work which shows the basic morphology and anatomy of a female wasp.
The sand wasp Ammophila sabulosa has an exceptionally long petiole. This Acanthomyrmex ant has a petiole and postpetiole. In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita.
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]
Synoeca septentrionalis is one of five species of wasps in the genus Synoeca. [1] It is a swarm-founding wasp that is also eusocial, [2] exhibiting complicated nest structure and defense mechanisms [3] and a colony cycle including a pre-emergence phase and a post-emergence phase. [4]
The polydnavirus replicates in the oviducts of an adult female parasitoid wasp. The wasp benefits from this relationship because the virus provides protection for the parasitic larvae inside the host, (i) by weakening the host's immune system and (ii) by altering the host's cells to be more beneficial to the parasite. The relationship between ...
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 ...
