Breeding fruit flies

An easy summer science project. Well, actually this is the third time we've done it and the first time it's worked, but it was easy once the conditions were right! We were doing life cycles, very clearly seen in fruit flies as their life cycle is around two weeks.

First some lovely rotten fruit in a jar. "Lovely," think the fruit flies. "We'll lay our eggs here." Within a few days:

Larvae! Then pupae:

And finally:

The adults have been on the fruit long enough to breed again and lay eggs so we'll release them and see if we get a second generation!
