One of the first butterflies I put on my site was a tiny
Ceraunus Blue Butterfly
found it laying eggs on Vigna luteola. Those pictures were so awful that
when I got to plants they weren't worth using to make a page on.
have a yellow flowered weed in my yard that I've paused to ponder, and
even photograph, from time to time, but I always had other more urgent
updates to get to, so it's still on my lengthy list of things to make a
page about, or was until an email from J. B. Sherrick brought my
attention back to it.
Thanks J.B. I was outside getting more pictures of my yellow flowers
after I read your email identifying a yellow flower in my sites as Vigna
luteola, and I realized that I have Ceranus butterflies in my yard and
I'd completely missed them.
Wild Cowpea, or Vigna
luteola, is a vine. in this next picture you can see it twining around
another plant at the waters edge. Oh, those adorable bugs are
damselflies that rested briefly on the vine while I was watching the
are pretty, and butterflies fun,
but where there is food, which both flowers and butterflies are, there
are also predators:
The ambush bug
is looking for dinner,
and any butterfly
Another visitor I found walking the vine was this Brown Stink Bug,
Euschistus servus. These bugs eat the plant, not the caterpillars.
Speaking of caterpillars, that bug on the flower in my hand isn't
a green roly poly, it's a Ceraunus Blue Butterfly
This close up of the stem beside the flower has a LOT going on. Before
you read any more, take a look at it more carefully. How many creatures
are in it? What are they? There is a clue in the picture to help you
find one of them.
Let's see how you did. There are several ants, a
flower crab spider
, and a
Ceranus Blue Caterpillar. Under the second ant from the top are little
dark colored lumps. When you see those, look above them to find your
Some caterpillars are camouflaged so well that they're hard to see.
Their frass (caterpillar poop) can help you find them since sometimes
it's easier to spot.
Wild Cowpea, or Vigna luteola, has bright yellow flowers, and is a nectar source for Ceranus
Blue Butterflies. This butterfly has it's proboscis in the flower.
Wild Cowpea Seed Pods are long and hairy. I found this pair of
tiny black weevils on one of the pods. When time permits, I'll
give them their own page.
