|Spur-throated Locust, Austracris guttulosa, south-west Queensland;|
all the following photos were taken in this general area.
|Locust swarm; in fact this was just a tiny part of a swarm that we drove through for hours.|
Having unusually high internal energy levels from the sun, and from increased eating, forces them to keep moving, so they must keep eating. Under normal circumstances these great swarms are driven by the winds into south-eastern Australia; when the wind speed exceeds 11kph, they move with it. As they move into cooler areas, they stop moving and eventually all die. Meantime they’ve been laying eggs as they go, which until the next drought changes things, will hatch as 'normal' grasshoppers.
