Definitive New Book on Saproxylic Insects

“About a third of all forest insect species are saproxylic,” says USDA Forest Service research entomologist Michael Ulyshen.

Ulyshen recently edited a definitive new book called Saproxylic Insects: Diversity, Ecology and Conservation and wrote four chapters.


Go get ‘em silver flies!

We are busy this spring releasing our new biological control agent, the silver fly.

Do you remember that hemlock woolly adelgid has 2 generations each year? Our best predators so far all feed on the fall/winter generation. So, unless all the adelgid are eaten or die, come spring time a whole new generation emerges to feed and reproduce. We are hopeful that theses silver flies will put a real hurtin' on that spring generation so we can reduce adelgid levels and relieve the pest pressure on our hemlock trees year round.


Spring means...crawlers

This is the time of year when the progrediens generation of hemlock woolly adelgid (HWA) is out in full force crawling out of their white, woolly ovisacs and looking for a place to settle at the base of a nice green hemlock needle.
