third and final unknown for the day
This is the third unknown object found on a japanese maple today in Memphis, Tennessee. Is this an egg sac? It’s about an inch long and is suspended by a thin thread that spanned at least a foot between 2 branches.
Thanks,
Tim

Today we received a new identification request which led us on an identification search on BugGuide that ended with a new identification for this egg sac configuration:  the Basilica Spider,
Mecynogea lemniscata.
