Small Hive Beetle (Aethina tumida) on Sep 30, 2026

Description of specimen

Submitter does not have a specimen
EDRR Status: Local expert notified

Small Hive Beetle. 10 days ago I found one on the lid of one hive. I killed it, brought it home and took pictures. Yesterday, the pollen patties in 2 of my hives were infested with larvae (I didn't know to remove any pollen patties as I've never dealt with these). I don't have the adult beetle anymore, but I do have a bucket of drowned larvae if needed.
