How do we catch a fly - alive?

If I couldn't catch a fly I had to think of an alternative. Some people suggested I bought some maggots from a fishing shop and raised them to be flies, but I wasn't sure what sort of flies they would grow into or how I would catch them.

The solution was given to me by my friend Tom, who knew Robert who was working with moth larvae here at the University. I emailed him asking if they had any insects in their department that I would be able to use. We met up and Robert showed me some fruit flies that someone was using, which I thought would be too small and the moths that grew from his larvae, which looked about the right size. Here is a picture of one of the moths taken by Robert.

We must now wait until a larva grows into a moth and then we can feed it to the Venus flytrap!
