Spider egg sack hanging from thread - Agroeca

Spider egg sack hanging from thread - Agroeca
Hwy 365, York County, New Brunswick, Canada
June 13, 2010
Size: sack is 1 cm
While out doing my bird atlas and butterfly atlas square I spotted something dangling from a leaf, and found this. Charley's book mentions that some spiders do this and also add debris to cover the sack.


This image is similar to mine:

What do you guys think?

Moved from Spiders. On page 45 of Charley's book(1) there is an image of a mud covered egg sac belonging to Micaria limnicunae.

dangling egg sac
It certainly looks like a Theridiosoma egg sac, though I've never seen one covered in debris. Insects & Arachnids of Canada, part 23 doesn't mention anything about debris either. It looks like more research is needed.
