Callophrys henrici
Henry's elfin, woodland elfin
Callophrys henrici, commonly known as Henry's elfin or woodland elfin, is a small North American butterfly in the family Lycaenidae. The species exhibits distinct population groups with different host plant associations: Atlantic Coast populations feed on various hollies (Ilex species), while northern and Appalachian populations use redbud (Cercis canadensis). The species has shown recent range expansion in New England due to adoption of introduced common buckthorn (Rhamnus cathartica) as a host plant. It is listed as a species of special concern in Connecticut.
Philotes sonorensis
Sonoran blue, stonecrop blue
Philotes sonorensis, the Sonoran blue or stonecrop blue, is the sole species in the monotypic genus Philotes. This small butterfly is found in the southwestern United States and northern Mexico, inhabiting arid rocky environments. The species has a wingspan of 22–25 mm. Larvae are specialized feeders on Dudleya species (stonecrops), boring into leaves. The subspecies P. s. extincta from the upper San Gabriel River wash was declared extinct in 1970 after three decades of annual sampling documented its disappearance.
