Hello. I was fortunate to see this praying mantis laying an egg case. I am wondering — how long until it hatches? How many young are likely to emerge? Are there signs that it is about to hatch?
I live in Scottsdale, AZ (Phoenix area), and this photo was taken on August 31, 2012.
Thank you for your web fascinating web site!

Preying Mantis lays Ootheca

Hi Lucille,
We are guessing that this might be
Stagmomantis limbata.  We hope one of our readers will be able to confirm or correct the species identification.  BugGuide states:  “Overwinter as eggs; hatch in spring or early summer; adults mostly in summer and autumn. Females in particular may sometimes survive well into winter.”  We suspect this ootheca may hatch in the spring and there may be several hundred young mantids that emerge.
