Cimbex connatus - Larva

Nice phat larva of one of our largest Sawflies. Found it on a small Elm (Ulmus) actually, but it must have fallen out of the Alder tree (Alnus) above it.
A day after finding and feeding it with leafs from the proper tree (Alnus) it started spinnig a cocoon:

    haha what a character, don't think I ever even saw any large sawfly larva at all, not even on a photo. Wonderful surprise. Posted 4 years ago

      At 40-45mm+ these are quite impressive and somehow seem to be harder/stronger (more muscular maybe?) than similarly sized caterpillars imho. Posted 4 years ago, modified 4 years ago
