Influence of photoperiod on thermal responses in body size, growth and development in Lycaena phlaeas (Lepidoptera: Lycaenidae).

ABSTRACT: Many ectotherms species grow faster but attain a smaller body size when reared under warmer conditions, a phenomenon known as the Temperature-Size Rule (TSR). This rule appears to be stronger in aquatic ectotherms than in terrestrial ectotherms. The difference could be related to difficulties for oxygen uptake in water, whereas on land, adaptive responses in body size may relate to seasonal time constraints. To assess the role of seasonal time constraints in temperature size response of terrestrial ectotherms, we reared the small copper Lycaena phlaeas at three temperatures (18 ˚C, 23˚C and 28˚C) and two photoperiods (16L: 8D and 12L: 12D). We examined whether differences in body size across treatments was related to (1) differences in growth and development, (2) differences in brea
