Your letter to the bugman:  Dear Bugman,
I was outdoors enjoying some fresh air and succulents  and noticed a pretty substantial spider web plus these very interesting white spiky spheres. I’m wondering if you can identify them?

Brown Widow Egg Sacs

Dear Melanie on the Irish Chain,
These are the Egg Sacs of a Brown Widow Spider, a species recently introduced to North America from Africa.  The Brown Widow is a relative of the native Western Black Widow, and since the introduction of the Brown Widow, populations of native Western Black Widows seem to have diminished, perhaps being displaced by a more competitive relative.
