I just learned that Steatoda grossa
spiders look a lot like black widows,
except they are more brown or reddish
and lack the hourglass. I've seen plenty
of black widows in Colorado and they
really do look similar. Nothing to worry
about though, apparently.

I found a whole family of these guys in
my worm compost which is a trash can
with holes drilled, full of ready to
harvest worm poop. I kind of freaked out
& squished them but now I see I was
overreacting. I wonder now what they
might have been eating in there,
