Cuckoo Wasp (Chrysididae)

The Cuckoo Wasp has a metallic appearance whose colors range from blues and greens to reds and yellows. They lay their eggs in the nests of other wasps or solitary bees instead of building nests or collecting food. Once the Cuckoo Wasp's larvae hatch, they consume the host's eggs or larvae. 

Moreover, the Cuckoo Wasp has an armored body that can roll into a defensive ball when threatened.

Cuckoo Wasps live in lush forests and arid deserts. Their parasitic reproductive strategy also naturally regulates the population of their host species.

Potter Wasp (Eumeninae)

Potter wasps construct small, vase-like nests from mud or clay, hence the name. They carefully mold the material using their mandibles and legs to create a sturdy and protective home for their offspring.

These wasp nests provide a nursery and a pantry for a single egg. Moreover, the wasp ensures that a paralyzed caterpillar or beetle larvae await the hatching wasp for a first meal. 

Potter Wasps prefer tropical locales, but they can survive different weather conditions. Their bodies are primarily black or brown with shades of yellow, white, red, or orange. 

Additionally, Potter Wasps are relatively harmless to humans and will only sting when provoked. Gardeners appreciate their help in controlling the population of pests such as caterpillars and beetle larvae. 

During winter, the Potter Wasp turns its nest into a refuge from the cold. The queen assigns larger cells to fertilized eggs that will become females and smaller ones to unfertilized eggs destined to be males.
