Onthophagus coenobita caught in a spider web, and rescued
I keep finding these little beetles, Onthophagus coenobita, not on the ground or sitting on a leaf, but tied up tightly in spider webs. The first time was on a walnut orb-weaver spider web by the railings in Warwick Gardens, cocooned in silk, and as I looked closely I could see it was still moving. I am a bit of a sucker for insects caught in webs and regularly deny a spider of a wasp, bee or grasshopper meal if I see one struggling in a web. So when I saw this beetle I snipped it off the silk and proceeded to help it untangle itself. I used a badge pin to carefully ease off the cocoon and all the while it was pushing itself out with quite a force for a little insect. After being freed it thanklessly flew off while I walked away filled with a sense of do-gooding.
A couple of weeks later I found another one in a different web… wrapped up in spider silk. I did the same again and it flew off. A few days later another one – this time it had already extricated itself from its silk tomb but needed help getting its final leg out. The next day another one dangling from a silk thread having completely freed itself and dreading the drop to the ground below. I began to wonder if this was the same beetle, living its life as the Houdini of the Coleoptera world, or if it was a game played with other beetles about who could escape the quickest from a dumb spider’s web before being eaten. Either way I still haven’t seen one just running along the ground.
