I assume these wasps are predatory and thus beneficial?

...assuming they don't sting me, of course!









I've noticed at least three separate wasps flying around my mother plant. In addition to this unlucky sucker, who was caught by a predator higher up the food chain (albeit MUCH smaller), a spider:

They are fine but what are they eating?

Much like the spider, they seem to feast on whatever flying insects get into my attic (where the grow box is) and then are attracted to the glow emanating from the air intake holes. So mostly small flies and/or moths. I've seen some gnats too, but nothing too infestation-like.

very nice pics.
