Ladybug pupa?

Asked June 29, 2020, 8:28 PM EDT

Found on apple tree leaf just as i was about to spray neem. Didn't spray yet. Are these ladybugs? Assume neem unsafe until adulthood. Thanks.

Sorry, not lady beetles.

They are new hatchlings of an invasive stink bug, the brown marmorated stink bug, Halyomorpha halys, sometimes abbreviated as BMSB. They are serious agricultural and home garden pests. Kill them on sight by drowning in soapy water.

For more info, see the following:

Thank you! I killed them.

Keep your eagle eyes open. You may have more.

Easy to spot when you know BMSB eggs are small white barrels whereas lady beetle eggs are golden spindles standing on end.

Apparently my routine spray of neem oil did not kill them. But maybe I just missed some spots on that tree. Would neem oil sprayed on a regular basis kill the larvae and pupa?
I rarely see BMSB around my home in the past two years.

Neem is unsafe for ladybugs and other beneficial insects at all life stages.

Conserving beneficial insects is a good reason to spray only when a problem exists. Then, too, some problems can be easily resolved without a spray. Caterpillars can be hand-picked, and aphids can be removed fro a plant with a harsh water blast. Both practices can be repeated as needed.
