On her daily rounds of weeding and observing in the Preserve, Glenda Denniston enjoys monitoring the smaller creatures, such as frogs, dragonflies, butterflies and others. Here are a few of her photos. Insects have emerged in full force, after being delayed for some time because of needed prescribed burnings of the prairie this spring. Notice the beautiful markings and the green/blue eyes of the cobra clubtail, named clubtail for the enlarged abdomen tip. they can be found at large rivers and lakeshores and are most abundant in June.
This Eastern tiger swallowtail photographed by Glenda is not the usually yellow variety of tiger swallow tails. Females can range in color from the yellow of the male to an almost solid bluish-black. The black form of the eastern tiger swallow tail may be an example of deceptive coloration, mimicring a butterfly with unpleasant taste.
