Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers.Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
Common names include the feather-legged lace weaver and the garden centre spider, the latter name being due to its frequent occurrence of this spider in garden centres. The species name is derived from the Latin pluma "feather" and pes "foot". Females grow up to 10 mm. They lack venom glands, and are therefore non-venomous.

Almost all spiders are venomous, but not all spider bites result in the injection of venom. Pain from non-venomous bites, so-called "dry bites", typically lasts for 5 to 60 minutes while pain from envenomating spider bites may last for longer than 24 hours. [9] Bleeding also may occur with a bite.
