hi what’s that bug?
this butterfly was seen along the “stump trail” area of grant’s grove, in king’s canyon national park CA, on july 14, 2014.
is it a california sister or a lorquin’s admiral? and what is the difference?
This is a perfectly timed submission as we just posted a closed-winged view of what we believe to be a Lorquin’s Admiral, but since we could not see a dorsal view, we can’t be certain. This is most certainly a Lorquin’s Admiral, and it is wonderful to get two views of the same individual. According to Butterflies Through Binoculars The West, on the Lorquin’s Admiral: “FW [forewing] apex has a linear orange patch that reaches the outer margin.” The same source states of the California Sister: “FW apex has a large round orange patch that doesn’t reach the outer margin.” That said, the same source indicates the two species look very similar, but the Lorquin’s Admiral is usually associated with willows and poplars, especially near streams while the California Sister is generally associated with oak woodlands.
