Scientific title: Ampulex compressa
Scientific classification: Phylum: Arthropoda Class: Insecta Order: Hymenoptera Family: Sphecidae

What does it appear to be? The cockroach wasp is round 15-25 mm in size with lengthy curving antennae, a big thorax, and an oval stomach, which tapers in direction of the rear. The colours of this insect are very dramatic, as it may be a myeariad of metallic blues and greens.

Where does it dwell? The wasp is native to the tropical forests of Africa and can also be present in India and a number of the Pacific Islands.


In many species of venomous animals, the poison injected through a sting or a chew has advanced into way more than only a technique of killing prey and predators. In some bugs, the venom has develop into so subtle that it controls the conduct of the prey, affecting its motion and exercise.

The cockroach wasp is one such insect. This small flying jewel preys solely on the a lot maligned cockroach. Using its highly effective senses, it properties in on considered one of these unwary pests and administers two stings. When delivering a sting, the wasp faces the cockroach and curves its flexible stomach round to inject the venom.

The first of these stings is directed to the tiny nodes of the central nervous system placed within the insect’s thorax. These minibrains management the cockroach’s legs, and the wasp’s venom blocks their exercise, paralyzing the sufferer. This paralysis is barely short-term, lasting for about 2-5 minutes. This is greater than sufficient time for the wasp to ship its second sting, which requires the talent and precision of a mind surgeon.

Using its very delicate sting, it delivers a tiny dose of venom to a area of the cockroach’s mind, which impacts, amongst different issues, its escape refl ex. When it will definitely recovers from the paralysis of the first sting, the cockroach doesn't strive to flee for the closest cowl, however grooms itself excessively for round 30 minutes, whereas the wasp scuttles off to search for an acceptable lair. When the wasp returns, it bites offone of the lengthy antennae of the cockroach earlier than lapping on the hemolymph (insect blood) that flows from the severed appendage.

Then the wasp grabs the cockroach by considered one of its antennae stumps and takes it for a stroll, like a really docile pet, main it to the refuge the wasp discovered earlier. There, the wasp lays a single egg on the stupefied host. The cockroach, primarily incapacitated however nonetheless alive is sealed on this hideaway with small stones and different particles, not to forestall it from escaping (it has no urge to!), however to preserve it secure from predators. The wasp larva hatches to find itself sitting on a mound of self-cleansing food, which it begins tucking into.

After two days, the younger larva is large enough to tunnel into the host, and after 4 or five days, the voracious feeding of the larva takes its toll, and the cockroach dies. After about eight days, the wasp larva is prepared to pupate, and it spins itself a silken cocoon contained in the drying carcass of the cockroach. The grownup hatches after about 4 weeks and leaves the lifeless husk of its host.

Key Facts

  • There are round 200 species of cockroach wasps, all of which parasitize cockroach species.
  • The cockroach wasp is a parasite of the American cockroach (Periplaneta americana), which, confusingly, is definitely a local of tropical Africa that has been by accident transported around the globe. It is among the cockroaches a lot maligned by people, and it's an unwelcome visitor in dwellings all over the place.
  • Because the jewel wasp preys on the American cockroach, it was launched to Hawaii in 1941 as a organic management agent of this pesky species. Unfortunately, this scheme was not very profitable because the wasp could be very territorial and the areas during which they hunt are usually fairly small.
  • The stinger of the jewel wasp, like that of different wasps, is a modified egg-laying tube. On its floor, there are a variety of microscopic sense organs permitting the wasp to use it like a precision instrument. These receptors are used to good impact to hit a goal within the tiny mind of the cockroach.
  • The thoughts-bending venom of this wasp doesn't immediately management the actions of the cockroach. It simply renders the cockroach simply led so the parasitoid can lead it like a light-mannered hound.
  • Many parasitic wasps sort out hosts that may be carried to an acceptable brood chamber. The thoughts-controlling venom of the wasp permits it to use a bunch that's a lot too giant to be carried away.
  • If supplied different bugs related in measurement to the American cockroach, the jewel wasp will give them a cursory as soon as over however make no try to sting them.
  • Other kinds of parasitoid wasps inject venom immediately into the central nervous system of their host, however the jewel wasp is the one identified animal that targets the mind specifically.
  • The blood-mind barrier of animals stops chemical compounds from coming into the mind. The stinging technique of the wasp overcomes this impediment.
  • Grooming is basically vital to all bugs. Using their toes, they'll rigorously clear their total physique. This conduct permits them to preserve their exoskeleton free of doubtless illness-inflicting microorganisms.
  • It is feasible to mimic the eff ect of the jewel wasp’s venom by conducting a small operation on the cockroach’s mind, however the result's nowhere close to as refined because the chemical compounds launched by the parasitoid.
