Biosecurity Queensland (BQ) says it will redeploy aircraft to spray a 40 kilometre-wide swarm of locusts spotted in central Queensland.
Officers surveyed the area today after sightings around Clermont, north-west of Rockhampton.
BQ says the insects are moving south-east towards cropping areas on the Central Highlands.
Large-scale spraying was carried out around the state last month amid warnings of a locust plague.
