Seeing More Spotted Lanternflies Lately?

28 August 2024

I was beginning to think we were safe this year but now I’m not so sure. After surprisingly few spotted lanternflies (Lycorma delicatula) in July and August, there are suddenly more of them in the air and on buildings and trees. Uh oh!

Have you seen more spotted lanternflies, too? I think I know why.

• Their peak population was in September last year so we probably haven’t reached the peak yet. But it’s coming.
• Spotted lanternflies love heat and it has been hot this week. Yesterday’s high was 94°F –> 13° above normal.
• Why do I see them fly by my 6th floor windows? They love height as well.

Last year I mused on their love of height and heat. I sure hope their population doesn’t get so bad this year!
