What kind of bait could be used to attract insects?

Question

I have to collect insects for school, and, especially dragonflies are hard to catch, even though there's a ton of them around. Is there anything in the house, maybe sugar or something that will attract stuff like dragonflies, wasps, butterflies, etc?

If this is in the wrong section, I apologize. I never have had to ask something like this.

Answer 1

Use an apple or fruit. And some fruit juice maybe too?

Answer 2

Watermelon, sliced.

Enjoy the show!

Answer 3

Insects eat different things  research the food for each type.  If you use a plastic bottle with the top cut off and inverted into it, you can make a trap. For yellowjackets, some raw meat in the bottle will attract them.  You will need to be able to kill the insects maybe a spray.  A banana peel should get fruit flies,  sugar or syrup will get you houseflies.  Dragonflies are predators, they eat waterborne insects do some research.  Good luck.
