A miscellany from the last couple of days. Firstly a female Southern Oak Bush-cricket Meconema meridionale from south London today, one of many seen. These bush-crickets were discovered in Britain in 2001 having spread north from the Mediterranean. This is an adult, and the wings are tiny, so it clearly didn’t arrive in Britain by flight. But bush-crickets are sometimes found on parked vehicles and are amazingly good at clinging on at speed. It’s conceivable that it made it to London by just clinging on to some cross-channel traffic.
I don’t normally pay much attention to spiders when I’m on a survey but this big girl certainly grabbed my attention: 13 mm long and looking like the sort of thing you’d see imported in a bunch of bananas, not under a log in London. It turns out to be Steatoda nobilis, and true enough this species “has been repeatedly introduced from the Canary Islands and Madeira with bananas”! In the Harvey, Nellist and Telfer (2002) Atlas it only has four dots in Britain but a look at the latest map from the Spider Recording Scheme shows that it has made itself firmly at home in southern England in the last decade. It is obligatory to mention that this is a species which can inflict a painful bite if suitably provoked.
Finally, a beetle I could reasonably have expected never to see my whole life long: Oxytelus piceus. It lives in cow-pats and would not have been an unexpected sight to a Victorian coleopterist living in southern Britain. But the progress of the 20th century was tough on many dung-feeding beetles and by 1994 Hyman and Parsons were only aware of records since 1970 from West Norfolk and Monmouthshire, and made it a Red Data Book species. In a cursory search, I’ve not been able to find any other records from recent decades. It wouldn’t be surprising if it hasn’t been recorded in recent decades – the dung fauna is not exactly making a come-back. The specimen in the photo is one of two found at a light-trap in cattle pasture in Cambridgeshire on Wednesday night. Not for the first time, I’m thinking why don’t I go out on mothing nights more often. The beetles can be really interesting (and it is certainly more fun than poking through cow-pats).
