Metopius (wasp)
''Metopius'' is a cosmopolitan genus of parasitoid ichneumon wasps in the subfamily Metopiinae. They lay eggs inside caterpillars of Lepidoptera that are found in leaf rolls, and the adult wasps later emerge from the pupa. They are black and yellow striped and reach over in length. Their coloring may be mimicking potter wasp Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae.

Parasitoid Wasp
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) 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. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, the vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichneumon Wasp
The Ichneumonidae, also known as the ichneumon wasps, Darwin wasps, or ichneumonids, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species currently described. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution.Quicke, D. L. J. (2015). The braconid and ichneumonid parasitoid wasps: biology, systematics, evolution and ecology. Chichester: John Wiley & Sons, Ltd. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control. The distribution of the ichneumonids was traditionally conside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metopiinae
The Metopiinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae. Metopiinae are koinobiont endoparasitoids of Lepidoptera. There are 26 extant genera. A bulging shield-like face is diagnostic for members of this subfamily, but many members lack this character. Description Most Metopiines are medium to large ichneumonids. They have a bulging face and with no groove between the face and clypeus. In most genera the upper portion of the face forms a triangular process that extends between the antennae. Many have stout, robust legs and generally have short ovipositors. Larger species may mimic aculeate wasps in coloration and by producing buzzing noises when captured. Biology Metopiines oviposit into the larval stage of their host and emerge fully developed from the host pupae. Many metopiines attack leaf rolling caterpillars. The wasp's stout legs and smooth face may be used to help females push their way into the leaf roll so they may reach the host with their s ...

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Potter Wasp
Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Recognition Most eumenine species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof), but some species, mostly from tropical regions, show faint to strong blue or green metallic highlights in the background colors. Like most vespids, their wings are folded longitudinally at rest. They are particularly recognized by the following combination of characteristics: # a posterolateral projection known as a parategula on both sides of the mesoscutum; # tarsal claws cleft; # hind coxae with a longitudinal dorsal carina or folding, often developed into a lobe or tooth, and; # fore wings with three submarginal cells. Biology Eumenine wasps are diverse in nest building. The different species may either use existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
