I'm the vulture of nature photographers. I seem to get my best shots of nature that is dead, injured, displaced or in distress. This is some sort of sphinx moth caterpillar, I'm pretty sure. Most sphinx moth caterpillars have a spike at their tail end, making the family easy to identify. This one was on the pedestrian trail at Walsingham Park, looking very miserable to be exposed. He appeared to have a minor injury near his eyespots.

Someone just mentioned hummingbird moths, and I said I wasn't sure if they had them in Florida. Well, this guy is in the same family as hummingbird and hawk moths. He might even be one. I'll try to narrow down his exact species. Doesn't he look like an elephant seal here?

I moved him off the path and he toddled away. I think he'll be okay.
