VIDEO of Sleepy Orange butterflies by Annette Allor at Mount Pleasant on June 29, 2020.
The phenograms show the maximum number of individual butterflies of this species seen in the first eight years of the Howard County Butterfly Survey. From these graphs, one can see the number of broods of each species, when they are active, and the relative abundance of the species in each brood. The observed early and late dates are shown below The graphs can be used to anticipate the first sighting of a given species in the year and can help with identification.
