A mystery began to nag at me. Some trees in the hottest areas within cities were covered in insect pests and still looked vigorous, while other trees with the same pest densities withered.
Unless you want an itchy rash, your best bet is to steer clear of these little critters altogether. And if you’re a couple of scientists trying to insert a data logger into a nest filled with two hundred of them? Well, your best bet is to suit up.
For many years, scientists have used forest maps to focus their predictions about where these itchy caterpillars might spread. But, it’s becoming increasingly clear that the PPM doesn’t actually need forests. It just needs trees, and it’s willing to accept the ones in the front yard, thank you very much.

Pink-striped oakworms are chomping on oak trees in Raleigh right now and leaving piles of frass (poop) in their wake. Spot them on your trees by looking for branches with all of their leaves chewed off.
What would be the easiest citizen science project ever? Watching paint dry? Falling off a log? Maybe. But what would you, or anyone else, learn from that? We are starting a citizen science project almost [...]
A spider in the family Anyphaenidae has made its home on a twig infested with scale insects. Photo: Emily Meineke, Harvard University I think by now most people accept that we can’t hope [...]
Climate change is generally considered bad for people, earth’s biomes, and, of course, polar bears. But as the climate warms will all critters suffer? Will they all be affected the same way? No. In addition [...]
This is a guest post from our former student (now postdoc at Harvard) Emily Meineke. Through years of studying urban trees and the insects that eat them, we, the Frank lab, have discovered that warming [...]
