I have seen the young on my wisteria during the Summer months. Although I've never seen their egg case. Isn't that an odd place to build a nest?Thanks for Brandon's TP but I don't think I'll need it...
The "pile" is a Praying Mantis egg case.
Raggie, As a kid I took a pair of chop sticks and feed flies to a praying mantis. Does that count as a trick?
... But whatever you do not let a hungry mantis ride on your shoulder, unless your neck and ears are covered, they are meat eaters!
