This chemical is cantharidin, and in the past, it was used by the Chinese as natural medicine. These oil beetles usually have a black or blue body with a really large abdomen, and on its top half, you can see a waistcoat that is a remnant of the wings that never developed.

The main reason is thought to be the changing ecosystem which may have destroyed the habitat of these beetles.

The female creates a nest and lays eggs under the ground, and as soon as the eggs hatch, the larvae proceed to jump up and reach the wildflower. The larvae hitch a ride on the bees with the hooks present on their legs. When inside the bee colony, these beetles live a good life on pollen and nectar until turning into an adult.

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

This oily droplet contains cantharidin, a potent poisonous material that can cause blisters and swellings on human skin. You may have thought that its shiny body gave this beetle its name, but it's actually the oil droplets produced by it that gives it this name of oil beetle.
