Yesterday was a great fall day to be in the Cherry Creek Pollinator Habitat. Jody and I were weeding and doing a little bit of clean up. While we were doing this, we found a few Chinese praying mantids egg cases. They are roundish and look like foam. The Carolina mantid egg case is flat, rectangular shaped and smaller. Both mantids are found in Nebraska.
If you find praying mantid egg cases on your plants or in the landscape, you should leave them alone. Each egg case contain up to two hundred eggs. In the spring the nymphs will emerge and they look like tiny versions of adult mantids. These insects are beneficial because they eat insect pests. But they can also eat other beneficial insects as well.
