Abstract V elarifictorus ornatus ( S hiraki) O rthoptera: G ryllidae) display distinct wing variation, and a physiological trade‐off between reproduction flight muscles has been observed in long‐winged LW ) short‐winged SW females. To understand the basis of this trade‐off, we investigated difference food digestion capability digestive enzyme activity We found that efficiency conversion digested into body matter females was significantly higher than females, although there no approximate digestibility during first 12 days after adult emergence. Similarly, growth relative were The consumption only 6 emergence, suggesting enhanced ovary development is probably because elevated coupled with greater early stage Trypsin‐like whereas differences fresh weight midguts (including content) at 1, 3, or 5 h refeeding starvation for 18 h. In contrast, amylase varied depending on time lapse refeeding, being 1 but lower 3 refeeding. lipase displayed similar trend both an initial decline followed by slight increase; any
