Giant Water Bug Eggs

Giant water bugs (also known as “toe-biters”) have the largest eggs of any aquatic insect. The eggs pictured belong to species in the genus Lethocerus, and are usually attached to vegetation above the water line. The eggs of some of the other species of giant water bugs are carried on the backs of the males. These aquatic predators lie on the bottoms of ponds and streams, where they stalk and capture crustaceans, fish, amphibians and even young turtles. They then inject their prey with powerful digestive saliva and drink the liquefied remains. To watch a video of hatching giant water bug eggs, go to

    • Thank you, Marjorie. I used a Canon 7D camera with a 100 mm macro lens — my favorite lens.

    The giant water bug is so aptly described in Annie Dillard’s ‘Pilgrim at Tinker Creek’ when she is sitting on the bank and a frog deflates before her eyes.

    Thanks for the egg photo as now I will know what to look for-and what I am looking at if I find some!
