Nelson County, Virginia
Traveling around Nelson County over the past few days? You have probably seen those funny purple boxes hanging up in the trees. Some people thought they were kites, others markers for a party, but nope, they are insect traps!
“That is my understanding. But they are also attractive to the state insect, the Tiger Swallowtail as well. Perhaps an alternative design might be less attractive to the butterflies but still allow a means of monitoring the spread of this exotic pest, i.e. the Emerlad Ash Borer,” says Michael Lachance an agent with the VCE-Agriculture and Natural Resources’ Nelson County Unit. The traps aren’t actually to take the insect out, but rather to obtain numbers on how many borers have actually migrated to the area.
Here’s a post on the Purdue University website, that pretty much parallels what we are seeing here.
Thanks Paul for grabbing a shot of one of these.
