Liatris mucronata with Strymon melinus

Liatris with hairstreak

Here we have a Gray Hairstreak Strymon melinus perched on the blooms of Liatris mucronata aka Gayfeather.  The Gray Hairstreak covers much of North America and as far south as Venezuela. It is distinguished by the red spot on its hindwing. One interesting thing about this butterfly is that it bobs its hindquarters up and down while the head remains fairly still, sucking nectar from the flowers. Click on the image anf look closely at the larger image with more detail and you’ll see what I am talking about. This picture was taken July14 at Taylor Park near Lake Granger and shows one of the few Liatris that were actually blooming at the time.

Taken under low light conditions (I gotta figure out how to use the flash, I guess) here’s another one of the butterflies that have been hanging around the Gregg Mistflowers. (The other species is the Monarch.) The Agraulis vanillae Gulf Fritillary spends much of its life on the Passiflora spp. vine, especially as a caterpillar. As a result, the passionflower vines have been having a bit of trouble getting established this year.

Strymon melinus –  Gray Hairstreak sitting on a Viguiera stenoloba –  Skeleton-Leaf Goldeneye aka Resinbush. If you look closely you will notice the head at the bottom of the  butterfly and the tail sporting a couple of fake antennae that actually wiggle around quite a bit while it is feeding. Apparently this evolved as a survival  advantage – one can imagine that if a predator goes after the false antennae , the butterfly is free to fly away and pass on its genes to the next generation which is how natural selection works.
