Spring Insects

Just as the plants are springing back into life, so are the insects that feed on them.

A number of the tiny elm trees espaliered into the fence have numerous leaves covered by tiny sack galls. Inside each is some type of insect, although I’m not certain whether they are aphids or mites. The result is somewhat unsightly, but reportedly doesn’t do significant damage to the plant.

More concerning is the invasive spotted lanterfly, which for the first time I have spotted in nymph form. The fact that these are black rather than red indicates they are a still at an early instar; they will turn red when they molt in a few weeks, and then assume their winged adult form later in the summer. They love to suck the sap from newly growing grapevines, and I’ll need to put some effort into limiting their population so they don’t do too much damage.
