I’m currently seeing more hive beetles than I’ve ever seen in the past 20 yrs. since they first arrived in Australia. While I have no photos of the beetles themselves, this is what you find on new frames. The places where bees had them corralled into. The bees corral them into hiding places before propolizing them in. These photos show the stains the beetles leave on the frames.
I’m seeing a fair bit of this at the moment, especially now that I have a lot of new frames in my hives.
