Larger, more colorful, and stronger hoppers than earlier,
late-stage Spotted Lanternfly nymphs are nearing adult flight.

Spotted Lanternfly nymphs, hatched from an overwintered egg mass,
gather upon a black walnut tree branch.

Native to Asia and reported in growing numbers across southeastern Pennsylvania since 2014, these nymphs are the first I’ve seen on our small patch of Little Crum Creek — first individually in the milkweed garden and grass, and now most frequently together (in the absence of their preferred tree-of-heaven) in this black walnut.

Normally, I’d wait to collect and post images of each life-cycle stage.  But you might be seeing these early nymphs too. If so, posting sooner seems better than later.

The Penn State Extension provides all we might like to know about identification and management of these invasive newcomers.
