Blinded Sphinx

Moths of Pennsylvania


 This one was caught at Adam's house on July 8th. It came to the bug zapper light sheet around 10 pm.

Here's the bottom of the wings-


This is a Blinded Sphinx Moth, or Paonias excaecatus. We had to go back to some slightly older pictures for this Moth of the Week, as the weather here has been very rainy. As sphinxes go, this one is a pretty big one. The large eyespots on the back wings are used to scare off predators. The moth sits with its wings closed at rest and flashes them when startled. The Blinded Sphinx feeds on basswood, birches, elms, oaks, and poplars. Its wingspan is 3-4.5 inches.
