Again, I'm not sure if I have the right ID for this tiny caterpillar, seen in the ENMAX Conservatory at the Calgary Zoo on April 30th. Looks like it's enjoying a tasty fragment of leaf. Unfortunately, is was a gloomy, overcast day, so no sunlight was coming through the windows, hence the graininess (plus heavy cropping). Taking myself off for a few hours today, to try and give my painful arms a break from mouse-clicking.
