This lovely guy has been roaming outside on my house for the last 2 days, so I went running in to identify it today. Not quite sure yet how to ID male/female and atrica/duellica so I’m mining through the internet now …
Hi, welcome to Spider ID. 🙂 This looks like Eratigena duellica (there has been recent name changes regarding a few species in this genus). To determine gender I’d need a clearer view of the peldipalps (leg-like appendages near the spider’s mouth), the ends are enlarged on penultimate and mature male spiders. Sometimes there are other hints, like proportionately longer legs and smaller abdomens on males. I’m not sure with this one though.
Thanks for the help 🙂 He disappeared but I’ll try to zoom in on his/her peldipalps when I see him/her again.
