Scoliid wasps act as important biocontrol agents, as many of the beetles they parasitize are pests, including the Japanese beetle. Male scoliids patrol territories, ready to mate with females emerging from the ground. Adult wasps may be minor pollinators of some plants and can be found on many wildflowers in the late summer. [1]
Megacolia azurea is a species of scoliid wasp found in parts of tropical Asia. These are among the largest wasps and several subspecies have been described. [1] Their larvae are parasitoids mainly of Scarabeoid larvae. It is a member of the subgenus Megascolia (Regiscolia).
Once the beetle larva had been consumed the wasp larva builds a cocoon and pupates, emerging from the cocoon as an adult in the following spring. [4] The European rhinoceros beetle is the primary host for the mammoth wasp but it will also lay eggs on the larvae of other beetles in the Scarabaeoidea including Polyphylla fullo , Anoxia orientalis ...
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. [ 1 ] [ 2 ] Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae . [ 3 ]
The larvae are also known to partially consume prey and discard the carcass if another potential prey swims nearby. Their usual prey includes tadpoles and glassworms, among other smaller water-dwelling creatures. As the larvae mature, they crawl from the water on the sturdy legs, and bury themselves in the mud for pupation. After about a week ...
Females lay eggs in protected areas hidden among the abundant vegetation of these habitats, and upon hatching, larvae can be found swimming throughout the upper water column in search of hosts. [18] [19] Once an immature host is located, Arrenurus larvae loosely bind to their integument, and monitor them until the adult emerges. Host muscle ...
Haliplidae larvae have a long and slender body with a tough exoskeleton. They can be recognized by their specialized mouthparts , carried on a small head. The maxillae and labium are adapted to manipulating the algae the larvae feed on, while the mandibles contain a channel through which fluids are sucked out of the food.
The Spheciformes is a paraphyletic assemblage of insect families which collectively comprise the "sphecoid wasps", and includes about 10 000 species.Larvae are carnivorous. ...
