I have more than one species of these! This one I think is Dioctria linearis

Ken, I have another which I took the day after this one. It looks like the male Dioctria linearis to me, yellowish legs, same cream stripes on the abdomen. I usually find a pair, if there's a female there's a male around too.

Do you agree? There seems to be only female pics around.

It certainly looks to me like the same species Dioctria linearis. I haven't any confidence in whether it is male or female,
Ken

I have compared it with another 'pair' I have now, which have the same/similar legs as each other so I think they are male and female.

I just imagined the female having the broader abdomen, I think it was another species which has a broader female, D. rufipes

Mating pair

Which I am wondering if they are my other pair.
