Cuckoo Wasp

The Cuckoo Wasp is quite widespread and may be seen on mud walls or termitaria investigating nests of potential hosts, like we found here at the Xombana restaurant. It was such an amazing experience to see the Mason Wasp build its chambers and fill it up with caterpillars. We never thought that we will be so fortunate to also find a Cuckoo Wasp inspecting and laying eggs in it's hosts nests. I will have to end with our famous last words nature is just amazing,

 Cuckoo wasps are small to medium size with body length of 4-20mm, They are metallic blue or red but usually bright metallic green. They are parasites that lay their eggs in the nests of bees, wasps, and certain other insects, which are called their hosts. There are approximately 3000 species of cuckoo wasps throughout the world

Cuckoo wasps can be divided into two chief types based on their lifestyles: parasitoids and cleptoparasites. Parasitoids feed on the larva of the host and cleptoparasites "steal" the host's food. In both cases the host larva dies. The food-stealing behavior of cleptoparasite species resembles that of the cuckoo bird and gave rise to the cuckoo wasp's name.

Egg laying process

Most species lay eggs in nests of solitary wasps and bees, their larvae feeding on host's provision or larvae.

 

Cuckoo wasps are only seen occasionally due to their small size and secretive habits. However, in open, sunny habitats they are often abundant on flowers and small shrubs, where they feed on nectar. Cuckoo wasps often lurk near the burrows of their hosts, waiting for an opportunity to sneak in and lay an egg. They have a thick, hard cuticle (outer covering) that is covered with pits. The cuticle provides protection from stings and strong biting mandibles of host insects, which may attack the cuckoo wasp. In addition, the underside of the abdomen is concave and allows the wasp to roll up into a protective ball, another defensive mechanism. Although cuckoo wasps sting, their stinger is very small.
