Hallo everybody

I found this Anthrax in Southern Germany, crawling out of a bee-hole in a trunk. When I returned with the camera about 2 minutes later, I saw a bladder popping up and some sort of ''dust'' on the thorax. Within one minute, the bladder became a little bit yellowish and smaller, and the dust increased.

Of course the title is just a joke, but I think it may be some spores of some infection with fungus.

to be continued

I made a photo of that too. Watching the ''dust'' increasing, I wanted to make another photo, but there was a spider catching the Anthrax, so I got only one more photo, which is rather bad. But anyway, you can see the mass of greenish dust.

Perhaps someone knows something more


Best regards, Siga

I suggest that the dust is pollen from the bee's nest. It would be unusual for a fungal disease to produce fruiting bodies in the areas on the fly shown in the photos.

the spider is Salticus sp. (perhaps scenicus).

I saw the fly coming out of its exuvia, which was sticking in the entrance of the hole in the wood. Beside the less than two minutes, where I got my camera, I watched it all the time. And between those two minutes, I am quite shure it didn't move at all from beside the hole, its wings not yet grown to full size. No chance, that it picked up any pollen.
I also pulled out the exuvia afterwards. No trace of ''dust'' there.

Besides that, I saw the amount of ''dust'' increasing.

Thanks so long

Antheax anthrax, the smoky wings and poorly defined markings and more elongate body than usual can all be accounted for by its teneral condition
