In warm spots under hedges, I see, the first spring insects now begin to appear, timidly and tentatively, from the shelter of their cocoons1. Some few of them, indeed, like the lady-birds, the wasps3, and the bumble-bees, have struggled through the winter in the winged or perfect form, having hibernated4 among warm moss6 or under the bark of trees in favoured situations. These adventurous7 kinds passed through their larval and pupal stages last year, and a tithe8 of them live on with difficulty through the winter frosts, to become the mothers and founders10 of fresh insect communities as April comes round again. But by far the greater number eat and grow as grubs or caterpillars11 through the summer months, and when autumn approaches turn into cocoons or chrysalides, to lie by for the winter in a snug13 retreat, well wrapped up in a warm silky or woollen coverlet, and protected underground from snow or hoarfrost. As soon as cold weather approaches, these prudent14 insects retire from public life, cease from active pursuits, melt themselves up into a sort of organic pulp15, lose almost every distinguishable organ or feature, and remain dormant16, in a state of indefinite protoplasm, which gradually takes shape again as moth9, beetle17, or butterfly. Mummies we sometimes call them, but they are not even mummies, for they lose almost entirely18 their form and limbs; they tide over the winter for the most part in an all but structureless mass, which yet encloses the potentiality of rebuilding in due course the shape and members of the ancestral insect. Slowly new limbs grow out within the protecting chrysalis case, wings bud from the side, and the grub or caterpillar12 changes by degrees into the totally unlike image of the beetle or butterfly. As soon as warmer weather sets in, the winged forms emerge with the first sunny day from their broken shell. I have seen nettle-butterflies abroad in a spell of genial19 warmth in the last week of January; a brimstone has been tempted20 forth21 to seek his lady-love on St. Valentine’s Day; and fritillaries are abundant in early March sunshine. Lesser22 insects, whose names are enshrined in scientific Latin alone, often emerge from their mummy-cases even earlier than these familiar and conspicuous23 lepidoptera.
The moment they peep forth, lo and behold24! they find the plant world, for its part, ready decked to greet them. The very same morning that sees the first butterfly and the first bee on the wing, sees also the first crocus opening wide its shining cup in the full sun to woo them. The brimstone is no sooner out than the coltsfoot and the celandine and the bulbous buttercup spread their gold to allure25 him. And has it ever struck you that the plants, no less than the animals, pass through the winter period in the chrysalis condition? This is no mere26 figurative flower of speech; it is the scientific statement of a real and profound analogy. During the summer months the leaves of the crocus, the tulip, and the hyacinth have been eating and laying by, exactly as the caterpillar did, to provide material for next year’s flowering season. When winter blows cold, the leaves die down—the plant, as it were, retires underground into its bulb, like the caterpillar into the cocoon2, and there remains27, formless and organless, a mere pupa-like potentiality of future buds and blossoms. But when warm weather recurs28, the bulb once more begins to germinate29: it takes fresh form as a vigorous flower-head. Observe, too, that the flowering stem, like the winged stage of the insect, is the sexual epoch30 of the plant, an avatar told off, as the butterfly by the caterpillar, to produce the seeds which are the eggs of the species. In each case a certain definite period of time is passed in laying by material, in eating and storing only; then comes a quiescent31 epoch of rest and rebuilding; and this again is followed by a mature stage of marriage and reproduction. Notice, too, in either instance, that the reproductive stage is more beautifully formed and more attractively coloured than the mere accumulative and storing mechanism33.
What is thus true of the crocus and of the butterfly is true, to a great extent, of all plants and animals in temperate34 or cold climates. They enter every winter into a chrysalis stage, from which in early spring they emerge once more, still more beautiful than before, freshly adorned35 for the mating and nesting period. Trees lose their leaves, and withdraw their protoplasmic and starchy material in a shapeless mass into the permanent tissues; but they hold it there, ready to manufacture it once more into bright green foliage36 and tasselled catkins, into blushing apple-blossoms, or tall spikes37 of horse-chestnut flower, or pink bloom of elms, with the first spring sunshine. Squirrels hibernate5; moles38 sleep away the dead of winter; frogs retire to the depths of ponds; slugs bury themselves in the soil; dormice doze39 in well-lined crannies among the boles of hazels. Many species only tide over the cold weather, indeed, in the most potential form, as eggs or seeds; they are annuals, like the poppy or the aphides of roses. In such cases the whole race is represented for some months by its germs alone: one generation never sees or knows the existence of another. In other instances, somewhat higher, the species survives as pupa or as bulb, adult, no doubt, though in a relatively40 formless or indefinite shape, yet ready to come forth full-fledged and perfect at the first faint breath of returning summer. Still other kinds, again, struggle through as mature and fully32 formed insects, or birds, or mammals, and as evergreen41 trees or shrubs42, though they live for the most part a life of low grade, and on accumulated materials. Nature is almost dormant in our zone through the winter months; life is then one vast and varied43 chrysalis.
