The praying mantis clinging nearby in the cold isn't lost. She's finishing the most important work of her life.
The tan, papery lump is her egg case. She whipped it out as a liquid froth and it set in the air, and inside, stacked in a column of tiny chambers, are more eggs than you'd guess.
Insulated. Waterproofed. Built for a winter she won't be here for.
The case rides out the cold glued to your stem, and on a warm day in late spring it pours out a crowd of mantises the size of mosquitoes.
๐ Whose case is it:
- Round, foamy, walnut-sized โ Chinese mantis, introduced
- Long, narrow, with a ridge down the middle โ Carolina mantis, native
๐ฟ What to do:
- Leave the stem standing through winter
- If it has to come down, tie the case to a stem or fence outside at the same height, out of the wind
- Keep it outdoors โ a warm room hatches it months early, with nothing for them to eat
She spends her last strength on a box of froth. Everything she was is inside it. ๐
