Fun facts

1

It arrives at a dead animal just a few hours after the flies. Then it eats the fly maggots so its own babies get more food.

2

Its larvae are black. When they are big enough, they drop to the ground, dig into the soil and change into grown-up beetles.

3

It looks a lot like a kind of bumblebee, with a black head and a yellow middle.

4

Scientists who solve mysteries sometimes study these beetles, because they come to dead animals at a known time.

5

Grown-up beetles spend the winter resting and come out again in spring.
