I love this site! I’ve already emailed the link to several friends. Here are a couple of pics I took at my home. I think I’ve narrowed these little critters down to a ‘White Lined Sphinx Caterpillar’. I understand that pillars go through color changes through their development. Are both of these the same species? Anyway, this little guy was crawling through the mulch under some bushes in late April in south Texas. Did I mention I love this site. I’ve got some more strange bug pics to contribute later. Thanks,

Hi Lance,
These caterpillars are indeed both White Lined Sphinx Caterpillars.
