Adelpha californica
California sister
Adelpha californica, the California sister, is a butterfly species in the family Nymphalidae found in western North America. Adults are active from March through November, with one to three generations per year depending on conditions. The species is unpalatable to predators and serves as the model for a large mimicry complex involving other butterflies. Larvae feed exclusively on oaks (Quercus), particularly canyon live oak and coast live oak.
Dryadula phaetusa
Banded Orange Heliconian, Banded Orange, Orange Tiger
Dryadula phaetusa, the sole species in its genus, is a Neotropical heliconiine butterfly recognizable by its bold orange and black banded wing pattern. It ranges from Brazil to central Mexico, with occasional summer vagrants reaching central Florida. The species exhibits sexual dimorphism in color intensity and participates in Müllerian mimicry complexes due to its unpalatability to birds.
