This ichneumonoid wasp is the test subject for my use of the bugalien bug catcher. It's a clear plastic pac man that you clomp over the insect or spider you want to catch. So far it's only worked for me for relatively large and slow bugs.
I like that it allows you to catch and release beneficial insects like this one without harming them. Although you could easily mishandle the clomper and maim a bug in the attempt to catch.
