What's That Bug? does not endorse extermination

Purple and orange caterpillar
September 1, 2009
Hello,
I found this odd little caterpillar on a Black Locust tree near my house in south-western Pennsylvania. I tried searching through books and the internet, hoping to find out what this little guy is with no luck. [S]he is about 2″ long. Hopefully you can help identify the bugger!

Dear Rebecca,
We started by searching the Owlet Moth Caterpillars on BugGuide, and then progressed to the Prominent Caterpillars.  Eventually we identified your Black Spotted Prominent Caterpillar, Dasylophia anguina, on BugGuide.  Distinguishing features according to Craig Biegler on BugGuide
include:  “the black ‘shoulder’ spot, shiny black ‘button’ on A8, raised rear end, elongated anal prolegs.”  The Caterpillars of the Eastern Forests website indicates:  “Splendidly rendered in shiny lavender, orange (or red), yellow, and black; both color and pattern variable. Head orange and unmarked. Middorsal and 2 or 3 subdorsal and supraspiracular stripes, these thin, broken, and black; subdorsal stripe orange, broad; spiracular stripe lemon, broad. Eighth abdominal segment with black dorsal button. Subventer with line of raised shiny black spots just above legs. Food: lead plant, locusts, and other legumes. Caterpillar: June to October; apparently 2 generations.”

    I have a 6 legged (caterpillar) there are no legs mid section or on back section. It is shiny black with brown squares …one square on each side of segment. It looks segmented and the first couple separated segments have white between it. The head is very small…There is no hair no antennas nothing else.
