Loxosceles rhymes with with isosceles, which you may remember from geometry is a type of triangle. The words are similar for a reason.
Loxosceles actually means slanted legs. If you look at a brown recluse from the side you can see how the body sits low and the legs angle up to a point. It's that angular, slanted shape of its legs that give the brown recluse its scientific name.
Two more distinct features of brown recluse legs:
- No spines: Unlike many other spider species, loxosceles does not have spikes or spines on its legs. They are smooth.
- One color: Some spiders have multi-colored legs, but loxosceles keeps it solid -- no stripes and no patterns.
If your spider doesn't have these legs then it's definitely not a brown recluse. If you find these leg characteristics similar to your spider then look into its eyes, all 6 of them.
