Welcome to my Butterfly Bucket List for July 2015. This month I’m highlighting the Pearl Crescent (Phyciodes tharos), a small butterfly that’s been flitting about in my garden since late spring. Its average wingspan is about 1.5 inches (approximately 3.8 cm). The Pearl Crescent is an orange and black butterfly, colors which appear to be very common in this part of the country as far as butterflies are concerned!
These butterflies flit around all over the place, rarely sitting still long enough to get close enough for a good photograph. I usually find them during the mid-afternoon when the sun is really beating down on the vegetation. They tumble from one plant to another looking for nectar or just to bask in the sunshine. When one finally comes to rest I make a stealthy approach and take a few quick shots while I’m several feet away…just in case it decides to flutter away before I can get near enough for a good close-up. Then I creep a little further, get the camera as close as I can, and begin snapping away until the butterfly takes off again. I never figured I’d become…the Butterfly Stalker!
Pearl Crescent Butterfly Facts
- Adult Pearl Crescents feed on nectar from a variety of different plants including: Black-Eyed Susan (Rudbeckia hirta), Butterfly Weed (Asclepias tuberosa), Shepherd’s Needle (Bidens alba), Sedum (Sedum spectabile), Aster (Aster) and Purple Coneflower (Echinacea purpurea).
- Caterpillar hosts include Frost Aster (Aster pilosus), Texas Aster (Aster texanus) and Smooth Blue Aster (Aster laevis).
- The Pearl Crescent is found just about everywhere in the United States except for the west coast.
- Pearl Crescents are brush-footed butterflies of the Nymphalida family.
This Pearl Crescent butterfly looks like he may have escaped the clutches of a predator at one point. He’s lost bits and pieces of his wings.
I’m especially intrigued by the butterfly’s antennae. The colors seem to alternate black and white. They’re very attractive! They also come in very handy. According to Gardens With Wings:
“Butterfly’s have one pair of segmented antennae. The basic shape is clubbed, meaning the segments increase in size as it gets further away from the head. For butterflies, this usually creates a club like appearance on the tip of the antenna. Butterfly antennae have chemoreceptors that are used for assessing the environment’s physical and chemical properties. Chemoreceptors are similar to the taste buds on our tongues. They are open nerve endings that transport the information to their central brains for translation. For example, butterflies use their antennae to detect which plants are producing nectar and males can sense pheromones from females of the same species. Near the base of the antennae, in the second antennal segment, there is also a very important organ called Johnston’s organ. It is used for balance and orientation during flight. With an antenna lacking, butterflies may be unable to fly in a particular direction and may end up flying in a circular pattern.”
Thanks for visiting my Butterfly Bucket List post for the fourth Sunday of July. If you’d like to take part please do so! The meme posting day is the 4th Sunday of each month, but that’s not a hard-and-fast rule. Feel free to post your sightings any time within the following week. Just put a link to your post in the comment section of this post. I look forward to seeing the butterflies, moths and caterpillars that have stopped by your garden during the past month!
