Deraeocoris signatus nymphs developed to adults when provided with cotton tips or squares plus cotton aphids ( Aphis gossypii Glover) or aphids only. Nymphs fed only on tips or squares all died within 3 d. Adults supplied with aphids plus tips or squares survived about 9 d longer than adults supplied with tips or squares only. Females provided with aphids produced eggs but females denied aphids did not. These findings, together with an absence of observed damage to cotton, warrant the exclusion of D. signatus from the complex of sap‐sucking bugs considered to be damaging to early‐season cotton in eastern Australia.
