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.
The parasitism pressure exerted by ichneumonids can be tremendous, and they are often one of the major regulators of invertebrate populations. [20] [21] It is quite common for 10-20% or more of a host's population to be parasitised (though reported parasitism rates often include non-ichneumonid parasitoids). [22] [23]
Commonly known as cuckoo wasps or emerald wasps, the hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or kleptoparasitic wasps, often highly sculptured, [1] with brilliant metallic colors created by structural coloration. [2]
Wasp season is typically between March and November but the bugs are especially active now after a mild winter and spring. “This is a really big year for wasps,” said Lynn Kimsey, director of ...
Jean-Baptiste de Lamarck, in his 1809 Philosophie Zoologique, treated the insects as one of nine invertebrate phyla. [23] In his 1817 Le Règne Animal , Georges Cuvier grouped all animals into four embranchements ("branches" with different body plans), one of which was the articulated animals, containing arthropods and annelids.
