May 1- I do not recall seeing them flying this early in southern Illinois in past years- the Eastern Tigers are flying with the Lilac blooms as usual and the Black Swallowtails are looking for wild carrot with the first real spring days- only males so far this season!

The zebra swallowtail is one of the first butterflies we see each springtime here in our woods on the edge of Cincinnati. This year I saw our first around May 5. They normally have two or three flights each summer in our region.
The zebra ST is a real beauty flying through the nectar garden and we planted several Paw Paw trees (Zebra ST host plant) along the forest edge to try to entice them to make a colony here.

I absolutely love this butterfly. Over a decade ago, these butterflies were incredibly common in this part of Louisiana. Unfortunately, they completely disappeared over a two-year period despite an increase in Asimina triloba numbers throughout the area.
It was really sad. One year (and several before), there were zebras in almost every patch of open woods in the area. The next year, there were just a few in a couple of forests. The following year, none. We still do not know what caused them to disappear. However, that was the first year that public and aerial spraying commenced for mosquito abatement, followed by a couple of devastating hurricanes.

We had never seen one of these before until today on our late blooming daylilies. We didnt know where to begin to find out what it was called but it was about the same size as the yellow and black eastern swallowtails. we thought the stripes look like a zebras so we searched for black and white zebra striped swallowtail butterfly and sure enough pics popped up of this same butterfly we saw and it's called a Zebra Swallowtail! Just Beautiful! this made our afternoon!
