MALE BOBOLINK IN SUMMER PLUMAGE.
Notes
May Twenty-second
Look intently at the bottom of shallow streams or ponds and you will see what appear to be small twigs and sandy lumps moving about like snails. These are the larvæ of the caddis fly. Pick up one and poke the creature with a straw. You now discover that it lives in a case made of gravel, or sand, or tiny shells, or pieces of bark, all glued together in a perfect mask.
