I love praying mantis' - they're so mysterious looking!
We just had one sit on the rear view mirror of our van, and it stayed there through about a 10 mile trip! It was hilarious, and hubbie almost drove off the road a couple of times catching a look at her!
Thanks for all the suggestions. I didn't want to get the fish tank out and all that stuff so I let her go. She was in the same spot all day today, good hunting area! They are the most remarkable insects. I love watching them hatch and drop. I was not sure if I could provide the right habitat and would hate to make a mistake and kill her. We bring in some of the monarch catepillars every summer and watch them turn into butterflies but they don't need much care and can sit on the kitchen table where they are always visible! If the mantis keeps coming back to the same spot I'll keep you posted. Mantis's don't live in Canada? Thanks again.
