Black and Yellow Caterpillar
Help! I found a couple of these at Lake Tahoe, I followed them around for awhile, then said goodbye. I’d really like to know what kind it is and what it will turn into.
Until someone informs us otherwise, be believe this to be the Spotted Tussock Moth Caterpillar, Lophocampa maculata, formerly Halisidota maculata. Many times the caterpillar has black tufts along the dorsal ridge, but we have located an image online that resembles your specimen.
