Pale green assassin bug habitat and feeding?

A sweet customer and regular at the Starbucks I work at in central IL, USA brought me a bug she caught in her garden today. Ive watched it long and hard and have come to the conclusion that it's a Zelus luridus - pale green assassin bug nymph.

My question is what kind of habitat and food should I prepare for it? I already have six tarantulas and a praying mantis, so I have fruit flies and crickets along with an extra critter keeper on hand with some Coco fiber substrate. Think this will satisfy my newest bug?
