In their metamorphoses they resemble the orthoptera, and are active through life.
"On the Origin and Metamorphoses of Insects"
Sir John Lubbock
In the orthoptera, and among those insects in which the changes are gradual, the mouth of the so-called larva resembles that of the perfect insect, and the principal difference consists in the presence of wings.
"On the Origin and Metamorphoses of Insects"
Sir John Lubbock
In the wingless species of orthoptera there is little external difference, excepting in size, between the young larva and the perfect insect.
