Finally! In the past week, the sun’s come out and so have the growing degree days (GDD). In fact, we have added 80 GDD (base 50 F) in Wooster since Monday alone. We pay so much attention to GDD because it is the primary driver of phenological development for plants. But did you know that it also determines insect lifecycles as well?

It’s like a scene out of the 1992 classic horror movie Candyman in the vineyard this fall. Yellow jackets, hornets, bees, wasps (1; Fig. 1)… but I promise, it’s the sugar content in the grapes and not because we’re summoning a man with a hook for a hand.

A natural wonder will occur in 15 states this year: the emergence of the Brood X, 17-year periodical cicadas! Also known as “17-year or 13-year locusts” the last mass emergence of these insects occurred in 2004. Now, 17 years later, the immature cicadas will emerge from the ground, molt one last time to gain wings, and “sing” loudly to find mates and lay eggs in trees and woody shrubs.
