Hi all. I live in MN and have my orchids outside in the summer. I noticed there are a lot of little black wasps (1/4" long) flying on and off my Dend. nobile orchids. They seem to hang out longer under the leaves than elsewhere, crawling around. They don't seem to be hurting the plants or doing much. Anyone have any ideas what they are or what they're doing?
