Dragonflies and damselflies are part of the order Odonata. The American rubyspot and the powdered dancer are some species living in North American marshlands. Ephemeroptera are mayflies, also abundant in water-rich habitats. Mantodea is the order of praying-mantids, with the genera Tenodera and Stagmomantis often found in North American marshlands.
Diptera refers to the insects that have a single pair of wings, including flies and mosquitoes. Many diptera insects use the water for reproduction, where they lay their eggs and live during their larval stage. Hymenoptera includes ants, wasps and bees. Species living in marshlands include members of the genera Bombus, Dolichovespula and the carpenter ant Camponotus.
Coleoptera include all beetles, many of which are found in marshlands, especially during their larval stage. Example of Coleoptera living in marshlands include the riffle beetles (family Elmidae), crawling water beetles (family Haliplidae) and the water scavenger beetles (family Hydrophilidae). Crickets, katydids and grasshoppers are part of the order Orthoptera, with several species living in marshlands, including members of the genera Orchelimum and Pterophylla.
Lepidoptera include butterflies and moths, with more than 3,000 species in North America alone. Common species in marshlands include the marsh fritillary, the salt marsh moth and Henry's marsh moth. Trichoptera are flies that spend their entire larval stage underwater. Although aphids are more common near food crops, these diminutive plant-sucking insects are part of the order Hemiptera and are also found in marshlands.
