Love your site. Some friends are living in Ocean Park, Puerto Rico, and took this beautiful picture. There was an unidentified caterpillar on ‘caterpillars 1’, but then i found the same one again on ‘caterpillars 4’ identified as the tetrio sphinx. i also found this site very informative http://www.silkmoths.bizland.com/Sphinx/ptetrio.htm thanks!
We generally turn to Bill Oehlke’s fabulous website when we need a Sphinx Moth identified.
