| Historically, the dynamics of grasshopper populations, especially nymphal mortality, have largely been attributed to variations in climate. |
| In insects, the general view is that juvenile hormone maintains larval and nymphal characteristics in developing insects and suppresses metamorphosis into adults. |
| Treatments began on 28 July, later than in the 1996 experiment because nymphal hatching was delayed. |
| Nymphal mirids are very tiny, delicate creatures which may not resemble the adults very much. |
| In September, uninfected survivors were all adults while collaborative females typically retained a nymphal phenotype. |
| Like many New World romaleids, these insects, which are called bush locusts, are often social in the nymphal or hopper stage and become more solitary as adults. |
