Hazelnut Sawflies
It’s normally a little disappointing to find an ichneumon wasp in one of my rearing containers, since that generally means I failed to rear whatever insect I was trying to rear. So when this one appeared yesterday… …I braced myself … Continue reading

Life in a Wingstem Stem
On May 8 last year, Julia and I visited her family’s land in Hocking County, Ohio (which we’ll be doing again today, as it happens), and for whatever reason, a little clump of dead wingstem (Asteraceae: Verbesina alternifolia) stems from … Continue reading

Green Wasps from a Green Island
