W is for wandering spiders (family Ctenidae)! #DailySpider
This is Phoneutria, one of the few spiders with venom that is very dangerous to humans.
Though we do have a few wandering spider species in North America, Phoneutria is only found in Central & South America.

Here is a great photo and blog post about Phoneutria by @wizentrop! (Note that he did not actually get bitten).

Phoneutria are quite defensive & will bite readily if threatened, but not all bites are severe.
During fieldwork in French Guiana, @Ibycter had 2 assistants bitten by these spiders (hiding in boots left out overnight). Both bites were painful & unpleasant, but not too serious.

Today's #DailySpider is the brown recluse, Loxosceles reclusa (family Sicariidae).
These secretive, six-eyed #spiders are almost certainly the most feared & misunderstood in North America.

Spiders in the genus #Loxosceles* are considered medically important because their venom can be harmful to humans (unlike that of the vast majority of other spiders).
*There are several species in North America. Pictured here: the Arizona recluse (L) & Big Bend recluse (R).

Recluse spiders are not aggressive. They do not go around looking for people to bite. They feed on insects & other arthropods, not human blood. #DailySpider
