Observations were made on a caged batch of Schistocerca gregaria from a swarm which invaded Antalya (TR) on 1988‐12‐03. Females did not change their colour, and this might be a sign of lack of sexual maturity. Only 1.5% of the eggs deposited were viable. Mortality, apparently due to exhaustion during the crossing of the Mediterranean sea and unfavourable local winter conditions, and inviability of the eggs produced are proposed as detectable causes of the decline of S. gregaria in Antalya.
