Evaluating a putative mimetic relationship between two butterflies, Adelpha bredowii and Limenitis lorquini

摘要: Abstract 1. A laboratory bioassay experiment was performed in order to investigate a long-standing putative mimetic relationship between two butterflies, the Lorquin's admiral Limenitis lorquini and California sister Adelpha bredowii (Lepidoptera, Nymphalidae). These butterfly species are commonly sympatric their broad distribution on west coast of United States. The wing colour pattern L. differs from patterns exhibited by its North American congeners, resembling A. instead. 2. feeding responses scrub jays Aphelocoma californica (Passeriformes, Corvidae) these prey types known palatable control, buckeye Junonia coenia Nymphalidae), were examined quantitatively. birds usually demonstrated long handling times before consumption, while manipulated consumed at same rate as control butterfly. also feather ruffling bill wiping after consuming they did not exhibit such behaviours J. coenia. 3. discriminate dorsal choice experiment. 4. Because moderately unpalatable captive discriminating choice, this suggests Batesian bredowii.
