The figures for many of the species include hoppers.
In many cases it was observed that pallid hoppers were sluggish and easier to catch than the normal hoppers.
The observations indicate that hopper colouring is, at least in some degree, associated with the colouring of the environment.
All the hoppers were comatose and none was seen in the act of feeding.
They are unanimous in saying that hoppers were far more numerous in 1930 and 1931 than they had ever been before.
This hopper included a translational offset mass in order to cause the tipping action that helped in forward propulsion.
He predicted28 that the hopper was unstable if the thrust occurred at maximum compression.
This may explain the occurrence of apparently unparasitised hoppers of the pallid type.
