| Popis: | We studied the relationship between wing stiffness and butterfly ecology and phylogeny. Nine species belonging to the tribe Theclini of the family Lycaenidae were selected and examined for the wing stiffness of dried specimens by a three-point bending test. It was found in Japonica lutea that the wing stiffness was not affected by the humidity to which it had been exposed, but was strongly affected by wing size and sex. Comparisons of sexual differences in four species indicated that females of patrolling species had stiffer wings than conspecific males, but that males of territorial species had stiffer wings than conspecific females. Finally, the wing stiffness was compared among males of nine species that use different mate-locating tactics, and the results revealed a tendency that males of territorial species have stiffer wings than males of patrolling species. These results, though including a few exceptional cases, are discussed from the perspective of ecological requirements and phylogenetic constraints on the species. |
