Illinoia liriodendri

2023 is shaping up to be “The Year of the Aphid.” At least, in southwest Ohio. I’ve already posted BYGL Alerts on aphids titled, Sticky, Dripping European Beech, and Sticky, Dripping Oaks. This Alert will be the third in the “Sticky, Dripping” series.

A question about flies buzzing a tuliptree prompted a site visit that revealed honeydew produced by tuliptree aphids was responsible for fly-by. However, the flies weren't untouched free-loaders. There were being infected by a fly-killing fungus.
