Thanks thats helpful. Have you seen one before and where did you find it?Check under pieces of debris that get warmed by the sun. Could also be sitting on the sides of houses.
Your lucky the last time i found onr was few weeks ago on a garden post i was amazed i thought London only had small jumpers although i recently found a massive zebra spider but on sundays ill use this information while looking thanks a lot guysJust found a mm of this species yesterday was jumping in my living room so I escorted it outside
Sunny walls or gardenchairs/tables seem to be most attractive.
yeh i just look at walls exposed to sunlight on sunny days.Haven't ever seen one (I'm in the US), so I just picked general urban hiding spots that jumpers tend to use. That's where I tend to have the most luck looking around for them here.
