Random Invertebrate Day #4: Mexican Caterpillars

Today's theme is caterpillars I saw in Mexico. The first was in Playa Ventanilla, close to Mazunte in the state of Oaxaca.

The rest are all from Lake Catemaco, in Veracruz State. Click on all pictures for a larger version.

I got this next one on video, as it was moving in an unusual way, pausing frequently to waggle both ends of its body

I suspect it might be a form of mimicry, copying the action of looking around with the fake head on its rear end.
