The fairly common Wall Crab Spider, Selenops mexicanus is not poisonous to humans (a bite can cause allergies in some people) and does not normally bite humans anyway. Like all spiders, he is a part of the total ecology of the world and I generally leave them alone in my house just like my geckos! I don’t always photograph when seen in my house, but did this one and online discovered his identification. For those in Costa Rica, the Spanish Common Name is “Araña de Pared” which translated to English is simply “Wall Spider.” I tend to photograph spiders more when outdoors or in a forest, thus I have a few photos of different spiders (about 20 species) in my Spiders gallery. Always interesting even if scary looking! 🙂 And remember, most are not poisonous!

¡Pura Vida!
