Only one genus is present in this family.
|Ero is the only genus found in middle Europe and four species
This attractive spider is very small; the size varies between 2.5 and 4 mm.
The legs usually have clear rings of pigment and the last two segments of their first forelegs are armed with a series of long alternated short spines.
This is a spider killer as her name suggests in German; Spinnenfresser (spider eater). She seeks out other webs and plucks the threads of the web with her legs to attract the prey. After a quick attack and lethal bite, with a quickly paralyzing venom, she sucks the victim dry through a hole in the legs of the victim.
Her eggs are laid in a cocoon surrounded with a wiry silk and are left to hatch on their own. Every female makes 2 -3 sacs. The sacs can be seen in late summer far more often than the spider itself.
