Megarhyssa macrurus, also known as the long-tailed giant ichneumonid wasp [1] or long-tailed giant ichneumon wasp, [2] is a species of large ichneumon wasp. [3] It is a parasitoid, notable for its extremely long ovipositor which it uses to deposit an egg into a tunnel in dead wood bored by its host, the larva of a similarly large species of horntail.
The species Pimpla rufipes has several synonyms, which include Pimpla hypochondriaca and Pimpla instigator. Pimpla instigator (Fabricius, 1793) has been permanently rejected under the International code of Zoological Nomenclature, since the original name Ichneumon instigator Fabricius, 1793 is a junior homonym of Ichneumon instigator Rossius, 1790, which represents a pimpline species outside ...
Wasp stinger, with droplet of venom. A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous
These ichneumon wasps have a thin black body, several whitish spots on the head, thorax, and abdomen and reddish legs. The antennae are long and thin. Females have a long ovipositor, which they use when laying eggs. The length of the ovipositor exceeds the body length. [5] This species is rather similar to Rhyssa amoena Gravenhorst, 1829.
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 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.
Synoeca is a genus of eusocial paper wasps found in the tropical forests of the Americas. Commonly known as warrior wasps or drumming wasps, they are known for their aggressive behavior, a threat display consisting of multiple insects guarding a nest beating their wings [2] in a synchronized fashion, and an extremely painful sting (rating at the highest level of 4 in the Schmidt sting pain index).
The species has a body length of 2 to 3 cm. Its markings mimic those of wasp species within the Polistes genus. C. brunnea exhibits a large amount of color polymorphism as many groups will mimic the colorations of specific wasps found within their respective region. [2]
