A big thank you to Craig Marks and all the good folk who participated in our Butterflies workshop and NABA Count. Their keen eyes in different locations made this year’s count better than preceding ones, with more species and far more individual butterflies counted!
Craig is Louisiana’s State Lepidopterist, and author of Butterflies of Louisiana, an excellent book about our State’s rich butterfly biodiversity that tell us about our various butterflies and where they have been sighted.
The lecture portion was very comprehensive and included some information about other insects that we might, and in some cases did encounter, with useful comparisons of distinguishing characteristics to help rapid identification. I was impressed by the clarity with which Craig explained the Batesian mimicry among the swallowtail butterflies! When I saw the Pipevine Swallowtails flitting over the Prairie trail, I felt I knew a good deal more about their business thanks to his lecture!
Intermittent Internet prevented the lecture portion to be broadcast by zoom concurrently, but we hastily filmed it for people who were unable to attend in person and shared that privately later. See the event flyer below for an overview of the program.
The count began auspiciously with observation of a large Monarch butterfly nectaring on some Brazilian Vervain just in front of the Visitors’ Center’s pond!
That made my day! Then our group’s exploration of the Prairie Trail area turned up a lot of butterflies! The Gulf Fritillaries seemed perfectly happy in the blazing sunshine.
I was also impressed by the quick turn-around of the results. We now have a preliminary count from Craig, NB This is yet to be finalized for submission:
“Here are the results I have so far, So 34 identified species which is both 5 more species than recorded before and pleasantly surprising to me. Thanks for everyone’s help on such a hot, humid day. My rough numbers indicate about 300 individual b/fs which is also higher than any previous year.
