I cannot identify these spiders (Uloborid species?) but they are very tiny (body 2 or 3mm – excluding legs). Spiders in this family do not have poison glands. They capture prey only relying on wrapping by silk. They build small incomplete orb web, mostly horizontal, usually not as perfect as those built by spiders in other web building families. Some species build web are considered as untidy. They use different type of silk than other spiders, known as cribellate silk which is woolly appearance. Those spiders sometimes find live in group with individual webs loosely connected.
This female was constantly harassed by males (sic) who wanted to steel her prey (a mite??) or do other things while she was distracted!!
