The nymph is the dominant life history stage of the mayfly. Different insect species vary in their tolerance to water pollution, but in general, the larval stages of mayflies, stoneflies (Plecoptera) and caddis flies (Trichoptera) are susceptible to a number of pollutants including sewage, pesticides and industrial effluent.
The origin of the word "dobsonfly" is unclear. John Henry Comstock used the term in reference to these insects in his 1897 book Insect Life, [1] but did not explain it. He also mentioned that anglers used the word "hellgrammite" for the aquatic larvae they used as bait, but the origin of this term is also unknown.
Eggs are laid on stones or vegetation near water, in clusters of up to 1000, especially on emergent water plants. The eggs are white at first but darken with age. They hatch after about six days, with the emerging larvae using a special hatching spike to open the egg case. The larvae fall into the water or onto the moist ground below.
