Brown spider with large white triangle / arrowhead on back

I was riding my bike in the woods and came back with a smallish brown spider with large white triangle on its back. The triangle also reminded me of an arrowhead. Triangle shape was equilateral. Triangle took up most of space on back. Sorry, no photo.

Is it poisonous? It was on my back pack...glad it did not land on me. I'm in the Ohio Valley area.


one of these?

Spiders are harmless unless you happen to be an insect.

or one of these?

Is that one harmless to humans?


Yes, as are essentially all North American
spiders. This is a harmless orb weaver. You can find some information about the Widows by going to the INFO page on widows or to the Article on them in the Forums / articles
