Dogwood Sawfly Larvae

The wife came into the house and informed me that some sort of white caterpillar was eating our red twig dogwoods by the driveway. What is with all these insects and caterpillars out here? I’m turning into an entomologist against my will.

So I went outside and this is what I saw:

It looked like only one branch of one red twig dogwood was affected so I snipped off the branch and dropped it in a pile of old dead leaves on the other side of the driveway. I went back inside and researched “white caterpillars of Ohio” and came up with ‘Dogwood Sawfly Larvae’ which makes sense since they are on my dogwood bushes. I’ll spare you all the details but they’re essentially harmless – the plant won’t die from them. They do damage but not enough to kill the plant, especially our large bushes. If I wanted to I could spray them with insecticidal soap or pick them off.

As I said, I chose just to cut off the offending branch they were living on.

One interesting note, their mid-life larval phase is when they are white – the whiteness makes them look like bird dropping, which camouflages them from predators.

Nature is cool.

P.S. Congrats to me, this is my 400th post! Somewhat befitting it’s a post talking about mother nature hating me.
