Cellar #spiders (sometimes also called daddy long-legs spiders as they superficially resemble crane flies, known commonly as daddy long-legs) are extremely successful and have spread across most of the globe, doing particularly well in houses. Certainly, with its diminutive body and hair-thin spindly legs, this #Pholcus phalangioides is the most common #spider in my house here in the UK. And they are the #arachnophobe's unlikely friend, as they feast mostly on other spiders, easily winning battles with species far bigger and more imposing than themselves. I just spotted this gravid (egg-carrying) female. Soon she will lay her eggs, about 25 in number, and carry them around in an egg sac until they hatch, whereupon she will stand guard over her brood of #spiderlings in her web until they are big enough to head out and fend for themselves.
The third photo here is of the underside.
