My Ero

I caught a spider on the bedroom ceiling on Saturday and was about to chuck it out of the window when I noticed it had four pointy tubercles on its abdomen. There aren’t many spiders with abdominal tubercles so I thought I’d have a go at identifying it. Lucky I did as it turns out to be one of the pirate spiders Ero aphana – only the third record for Bedfordshire!

Ero aphana

The Atlas of British spiders (Harvey, Nellist and Telfer, 2002) lists about 11 sites for this species, all on the heathlands of Dorset, Hampshire and Surrey. It is still a Vulnerable (Red Data Book 2) species but since the turn of the millennium it has ceased to be dependent on heathland and has been turning up in a wide variety of mostly dry habitats (houses, gardens, brownfield sites, etc.) and spreading as far north as Nottinghamshire. Map and further info on the Spider Recording Scheme webpage.

Many thanks to Ian Dawson for helping to identify this spider and for information on its status in Beds.
