Bug of the Day: Megalopyge opercularis

02Aug06

This post has nothing to do with physics, Stanford, or Berkeley. However, I wanted to share it anyway. I ran into this video on Youtube:

It is a clip of a “Puss Caterpillar,” the larvae of a Flannel Moth Megalopyge opercularis. Apparently it’s poisonous and in Mexico it’s called el perrito (tiny dog). Other specimins look a little like tribbles.

I feel a little guilty, so I’ll make a couple of obligatory Stanford/Berkeley references:

  1. If this caterpillar were at Stanford, it would have black fur. (That’s a squirrel reference for those who aren’t familiar with Stanford fauna.)
  2. If this caterpillar were at Berkeley, it would be on Shattuck with a cardboard sign asking for money.

My artists renditions of these caterpillars if they attended either Stanford or Berkeley:

    oh my goodness. i am not a fan of bugs that could eat small children if they felt so inclined … it’s as big as a catalogue of dodgy arnie quotes

    One of these bastards bit my daughter who is doing graduate studies in forestry restoration at LSU. She got nailed while measuring a tree. It was and is very painful with swelling and inflamation. Warning, do not touch these things, very nasty.
