after about five minutes the bee came out and flew into the net. It proved to be a solitary mason bee, and was doubtless forming a place to lay its egg, only, unlike the wasp, she would give the young grub pollen from the stamens of flowers to feed upon instead of green caterpillars. I remember seeing a mass of clay which had been formed into a wasp's nest by one of the solitary species, under the flap of a pembroke table in an unused room. A maid in dusting lifted up the flap, and down fell a quantity of fine, dry mud with young grubs in it which would soon have hatched into wasps, and revealed their rather strange nesting-place. I have in my collection a very interesting hornet's nest, which was being constructed in the hollow of an old tree. I happened to notice a hornet fly into the opening, and, looking in, there was a small beginning of a nest It hung from a kind of stalk and consisted of only eight cells, each having an egg at the bottom. I captured the two hornets, and though I watched for a long time no others ever came, so I imagine they were the founders of what would have been a colony in due time.
But we have been kept a long time engaged
