Illustrious greenbottle fly

A mother lays about 200 eggs at once, and she can do this up to 10 times in her life of about three weeks.

When it is warm, about 25 degrees, the eggs hatch in about one day.

It likes cool weather. At about 8 degrees, it is often the most common kind of maggot on a dead animal.

Doctors sometimes use its maggots to clean wounds, because they only eat dead tissue and leave healthy skin alone.

Scientists who solve mysteries use how fast it grows to work out how long ago an animal died.
