This native plant finder can help you find native plants that will attract the insects and other life you're hoping to entice. The associations listed are the research results of Doug Tallamy and other researchers. And as Tallamy says, plant for specialist insects and you'll attract generalists as well.
Off the top of my head, plants like canadian ginger, serviceberries, purple flowering raspberries (R. odoratus), and members of the worts can do a lot of restoration work in moderate to deep shade. Having a patch of grass that doesn't get mowed is a huge boon to many insects, as is leaving any mowed grass clippings around other plants as mulch. Lightning bugs in particular require grass debris or patches where it got so long it fell over to complete their life cycle.
