Question: Whats the difference between a cellar spider and a brown recluse spider?

ANSWER  The typical cellar spider has very long legs, a long slender abdomen, and usually hangs in webs. The brown recluse when full grown, and legs extended is about the size of a quarter (coin).  Brown recluse spiders spend most of the time hiding in dark, secluded places.

Brown recluse spiders are nearly uniformly pale brown to light brown spider. Their legs are not banded and not especially ”hairy”; the violin shape on the ”head region” is distinct, but many other spiders have this mark, it is not actually unique to the brown recluse.

Of course, when in doubt it is always safe to be cautious; it is of little value to over-react to the presence of any spider.  They are not aggressive animals, and usually bite when cornered or brushed against.
