At other times

G. E. Channing, « A Water Museum », St. Nicholas Magazine for Boys and Girls, vol. XII, part. II, New York, Scribner & Co., 1885, p. 784-785.

The caddis-worms in their odd little houses of sticks, and shells were always up to mischief; sometimes one would catch hold a patient snail and try to glue it to his house, and after a struggle, in which the strong snail would manage to get away. Mr. Caddis would hide his head in the grass and keep still, as if he felt very foolish and ashamed.
At other times they would have a wrestling match, and we would heartly laugh to see them push and tug one another about.
