Very common around the house at this time of year.
No interactions present.
Julus scandinavius and Ophyiulus pilosus are similar to T.niger (i.e. dark with pointed telson) but never have the contrasting pale legs seen in this specimen (but NOT in all T.niger specimens, though). Leptoiuls belgicus also occurs in western Scotland, and although usually has pale dorsal stripe can be entirely dark.
