Fruit fly capture device

Fruit Fly Trap

Build a fruit fly trap out of a 2-liter plastic bottle. Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

2 Weeks Later

Watch carefully, they're tiny, it happens fast. The females in your trap will lay eggs, and in a few days they'll hatch. Watch for the different stages - eggs, larvae, pupae, fruit fly. The entire life cycle only takes about 2 weeks.

Fruit Fly Colony

Use your fruit fly colony to feed a spider or praying mantis living in a Predator-Prey Column.
