The Life of an Insect: being a history of the changes of insects from the egg to the perfect being.
Insects
The common earwig, a name at which some, who little know the beautiful
traits in her character, are apt to shudder, still more closely
resembles the affection of a higher animal than does the spider just
mentioned. The following most interesting notice of her proceedings
was published by a writer[B] in the _Penny Magazine_ some time since.
He says: "About the end of March I found an earwig brooding over her
eggs in a small cell scooped out in a garden border; and in order to
observe her proceedings, I removed the eggs into my study, placing
them upon fresh earth under a bell glass. The careful mother soon
scooped out a fresh cell, and collected the scattered eggs with great
care to the little nest, placing herself over them--not so much, as it
afterwards appeared, to keep them warm, as to prevent the too rapid
evaporation of their moisture. When the earth began to dry up, she
dug the cell gradually deeper, till at length she got almost out of
view; and whenever the interior became too dry, she withdrew the eggs
from the cell altogether, and placed them round the rim of the glass,
where some of the evaporated moisture had condensed. Upon observing
this, I dropped some water into the abandoned cell, and the mother
soon afterwards replaced her eggs there. When the water which had been
dropped had nearly evaporated, I moistened the outside of the earth
opposite the bottom of the cell, and the mother, perceiving this,
actually dug a gallery right through to the spot where she found the
best supply of moisture. Having neglected to moisten the earth for
some days, it again became dry, and there was none even round the rim
of the glass as before. Under these circumstances, the mother earwig
found a little remaining moisture quite under the clod of earth, upon
the board of the mantel-piece, and thither she forthwith carried her
eggs. The subsequent proceedings were not less interesting; for though
I carefully moistened the earth every day, she regularly changed the
situation of the eggs morning and evening, placing them in the original
cell at night, and on the board under the clod during the day, as if
she understood the evaporation to be so great when the sun was up, that
her eggs might be left dry before night. I regret to add, that during
my absence the glass had been removed and the mother escaped, having
carried away all her eggs but one or two, which soon shrivelled up."
