Posts Tagged ‘Can on 50D’

Recently I did a posting that featured Eastern Tiger Swallowtail butterflies (Papilio glaucus)—see Swallowtails in the forest.  None of those butterflies seemed to be involved in searching for nectar and seemed content to take in minerals and water.

Last Friday I returned to that same location in Prince William County, Virginia and discovered that the butterflies were taking advantage of the few small flowers that were blooming. In the first photo, an Eastern Tiger Swallowtail was nectaring on the small bluets (Houstonia caerulea) that are sometimes referred to as Quaker Ladies. The butterfly was so low to the ground that it looked like it was dragging its “tails.”

The butterfly in the second image is a dark morph Eastern Tiger Swallowtail female. Females of this species are dimorphic—there is a yellow variant that looks like the one in the first photo and a dark variant that looks like the one in the second image. The dark morph female was almost flat on the ground as she gathered nectar from a very short dandelion.

As more flowers begin to bloom, I am sure these butterflies will have a better selection of sources of nourishment, but the early arrivers have to make do with a really limited menu of choices.
