What kind of spider is this
I can set your mind at ease, this is not a Brown Recluse or Black Widow spider. It appears to be a grass spider, which is not poisonous. These are very common and difficult to ID specifically from a photo.
These spiders can still bite but for most of the population the worst reaction would be similar to a mosquito bite. If you are particularly sensitive to insect bites or venom check with your Doctor to avoid any health issues.
