Homoploid Hybrid Speciation in an Extreme Habitat
TLDR
It is found that the alpine-adapted butterflies in the genus Lycaeides are the product of hybrid speciation, and adaptive traits may allow for persistence in the environmentally extreme alpine habitat and reproductively isolate these populations from their parental species.
THE LOCK-AND-KEY HYPOTHESIS: EVOLUTIONARY AND BIOSYSTEMATIC INTERPRETATION OF INSECT GENITALIA
TLDR
The authors cannot withhold a hearty assent to the conclusion of one of the most eminent of modem physiologists, who says that the hard parts of the male correspond so exactly with those of the female, that the organs of one species cannot fit those of another.
THE PONTIA DAPLIDICE‐ED USA HYBRID ZONE IN NORTHWESTERN ITALY
TLDR
Using the numerical techniques developed for hybrid zone analysis, populations of daplidice and edusa on opposite sides of the hybrid zone share more identical‐by‐descent alleles than do populations of phenotypically pure daplodice in, say, France and Morocco.
Compounded effects of climate change and habitat alteration shift patterns of butterfly diversity
TLDR
The interacting negative effects of human-induced changes on both the climate and habitat available to butterfly species in California reveal the decline of ruderal, disturbance-associated species, and indicates that the traditional focus of conservation efforts should be broadened to include entire faunas when estimating and predicting the effects of pervasive stressors.
Climatic trends and advancing spring flight of butterflies in lowland California
Many studies, largely from cool‐temperate latitudes, have investigated the relationship between the timing of biological events and changes in climatic conditions during the past few decades.

Abstract. Using the unusually well‐documented butterfly fauna of Davis, Yolo County, California, it is shown that the mainly native species commonly observed in gardens breed mostly or entirely on
Identifying units for conservation using molecular systematics: the cautionary tale of the Karner blue butterfly
The federally endangered North American Karner blue butterfly (Lycaeides melissa samuelis) and the closely related Melissa blue butterfly (L. m. melissa) can be distinguished based on life history
Increasing neonicotinoid use and the declining butterfly fauna of lowland California
TLDR
It is suggested that neonicotinoids could influence non-target insect populations occurring in proximity to application locations, and the need for mechanistic work to complement long-term observational data is highlighted.
