Here’s a pest you may have heard about, the Spotted Lanternfly (Lycorma delicatula). It is not a fly, but a planthopper. In the Order Hemiptera, Family Fulgoridae.

We can still see the remains of low temperature injury from a couple of weeks ago. Not to worry, the next set of leaves will cover up the desiccated leaves and stems.
