Cockroach egg parasitoid wasp

Cockroach egg parasitoid wasp

Evania appendigaster

A species of Evania, Also known as Common cockroach egg parasitoid wasp

Aptly named, the cockroach egg parasitoid wasp is known for parasitizing cockroaches. The females lay their eggs inside of the cockroach's egg casing, and when the larvae hatch, they can feed off of the cockroach eggs. This process of inserting the eggs requires quite a bit of physical effort and maneuvering lasting, typically lasting up to thirty minutes.

Species Status of Cockroach egg parasitoid wasp
Its native range is not known, but it likely originated in Asia. Today it occurs throughout the tropics and subtropics and in many temperate regions.

Life Cycle of Cockroach egg parasitoid wasp
Egg At this initial stage, the cockroach egg parasitoid wasp begins as an egg, usually oval-shaped and miniature. The eggs are typically laid in the host or near food sources, and their color, size, and shape can vary based on environmental factors. The embryonic cockroach egg parasitoid wasp develops within, preparing to hatch.
Larva Upon hatching, the cockroach egg parasitoid wasp enters the larval stage, characterized by a worm-like appearance. It is primarily a feeding stage, where the cockroach egg parasitoid wasp consumes food voraciously to store energy for the upcoming transformations. The larvae will molt several times, increasing in size after each molt.
Pupal As the cockroach egg parasitoid wasp transitions into the pupal stage, it becomes encased in a protective cocoon. Within this chamber, major body reorganization occurs. The cockroach egg parasitoid wasp is now dormant, undergoing metamorphosis, which includes the development of wings, legs, and adult body parts. The pupa may differ in color and form.
Adult Emerging from the pupa, the adult cockroach egg parasitoid wasp's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. The adult also shows significant changes in size, color, and behavior from earlier stages.

Habitat Preferences of Cockroach egg parasitoid wasp Through Different Life Stages
The adult cockroach egg parasitoid wasp are typically found near places abundant with cockroach populations, as females seek out cockroach oothecae to deposit their eggs. The preferred habitats for these adults include warm, humid environments like leaf litter, logs, or crevices in and around buildings. For the larvae, they develop within the cockroach ootheca they were laid upon, making them more challenging to find. To search for larvae, one would need to inspect the oothecae, usually attached to surfaces in hidden, sheltered areas within the cockroaches' environments. Pupal stages occur within the ootheca, thus not requiring an additional location change.
Rectangle
When is the Best Time to Observe Cockroach egg parasitoid wasp
Cockroach egg parasitoid wasp are more active during daylight hours; therefore, searching for them during the day increases the chances of observation and capture.
Rectangle
What is the Best Weather to Observe Cockroach egg parasitoid wasp
Warm and dry weather conditions are more suitable for finding cockroach egg parasitoid wasp because these conditions are favorable for the activity of their hosts and consequently for the wasps themselves.

How and Where Can You Find Cockroach egg parasitoid wasp at Different Life Stages
Adult Cockroach egg parasitoid wasp adults can often be spotted in flight or when they are searching for hosts on which to lay eggs. Look for them near places where host insects, like cockroaches, are known to reside, such as decaying wood, leaf litter, or in the cracks and crevices of structures.
Egg Eggs of cockroach egg parasitoid wasp are typically laid within the body of a host insect. Therefore, to find cockroach egg parasitoid wasp eggs, one must locate the host insects and examine them for signs of parasitism, such as the presence of eggs or changes in behavior.
Larva Cockroach egg parasitoid wasp larvae develop inside their host, so finding them involves identifying parasitized hosts. These may show signs of infection or altered behavior. Host insects might be stationary or exhibit erratic movements if parasitized.
Pupal Cockroach egg parasitoid wasp pupae may be found in or near the deceased host. When the host dies, inspect the immediate vicinity for the cockroach egg parasitoid wasp pupae, which could be concealed in nearby substrates such as soil or leaf litter.

Toxic to Animals

Cockroach egg parasitoid wasp utilizes its fangs to deliver a mild venom when biting. Though primarily targeted at incapacitating its prey, such as insects, the venom can cause localized pain and discomfort in larger mammals, including humans. The toxic reaction in affected animals can vary, with smaller creatures possibly experiencing more severe symptoms. However, due to the low toxicity of the venom, the bite is generally not considered dangerous to humans. Only in its adult stage does cockroach egg parasitoid wasp possess the capability to envenomate.
