Have you noticed an inordinate amount of ladybugs around lately?
It’s to be expected, according to Jennifer Frye, an invertebrate ecologist at the Maryland Department of Natural Resources.
“This is something that’s been happening more and more in the last couple of decades,” she says.
But these aren’t American insects. They are actually Asia natives that were first introduced to America in the early 1900s to control aphids, otherwise known as plant lice. The population began thriving here in the 1980s.
