This winged insect, whose delicate palate selects out the choicest viands, one while extending is proboscis to the margin of a drop of wine, and then gaily flying to take a more solid repast from a pear or a peach; now gambolling with his comrades in the air, now gracefully carrying his furled wings with his taper feet; - was but the other day a disgusting grub, without wings, without legs, without eyes, wallowing, well pleased, in the midst of a mass of excrement.
