I admit it: I clicked on a link this article from the The Courier-Journal because of the cute title. European wall lizards (Podarcis muralis) have invaded Falls of the Ohio State Park in Indiana, probably hitchhiking down the Ohio River to get there. Concerned about the impact those reptiles could have on native lizards species (something they enjoy eating, apparently), state biologists have begun trapping the lizards using strawberry jam. The jam entices the lizards, and the sticky substance surrounding them keeps them there until someone checks the trap. Native species are released, while the European wall lizards are euthanized.
