A female Loxosceles laeta spins its web. The two anterior lateral spinnerets (ALS) move between 8-13 times per second, while the silk thread is pulled by the posterior spinnerets. The silk threads are produced by a single pair of spigots, and compose the entire web.

This video is part of the supplementary material to the following article:
Recluse spiders produce flattened silk rapidly using a highly modified, self-sufficient spinning apparatus.
