Flight performance of tagged hornets. a Hornet and tag weight combinations resulting in hornets, on release into a field cage (3 m x 3 m x 2 m), being categorised as good (closed black dot) (n = 24) or poor (triangle) (n = 20) flyers based on flight behaviour. A hornet (cross symbol), with fresh weight = 0.49 g and tag weight = 0.28 g, is considered an outlier as caught & held in a hornet trap for over 5 h before its flight performance was assessed. b Percent of hornets (out of 43 assessed), grouped according to their tag:hornet weight ratio, demonstrating good flight performance on release into a field cage (3 m x 3 m x 2 m) or flight room (2 m x 2 m 2 m)
