I am inclined to believe that it must be so, while trying to count the visits paid to the nest in one hour by the parent tits those small tits that do the gardener so much harm! We know, on good authority, that the spider has a "nutty flavour"; and most insects in the larval stage afford succulent and toothsome, or at all events beaksome, morsels.
I wonder what the fair Lady Alicia intends doing about getting her crop off. Sing Lo will scarcely be the man to master that problem.... The Lord knows I'm busy enough, but I seem to be eternally waiting for something. I wonder if every woman's life has a larval period like this? I've my children and Bobs. Over my heart, all day long, should flow a deep and steady current of love.
On the other hand it is highly probable that with many animals the embryonic or larval stages show us, more or less completely, the condition of the progenitor of the whole group in its adult state.
Several instances are recorded where the oxwarble has occurred in man, always causing much suffering and sometimes death. One or more species of bot-flies occurring in the tropical parts of America frequently attack man. The early larval stage soon after it has entered the skin is known as the Ver macaque. Later stages as torcel or Berne.
So an imperative necessity presents itself: there must perforce be an initial larva form, capable of moving and organized for searching, a form under which the grub would attain its end. The Anthrax would thus possess two larval states: one to penetrate to the provisions; the other to consume them.
The naturalist includes as one species the several larval stages of the same individual, however much they may differ from each other and from the adult; as he likewise includes the so-called alternate generations of Steenstrup, which can only in a technical sense be considered as the same individual.
On the other hand, taking the caterpillar or bee larva, with their cylindrical, fleshy bodies, in most respects typical of larval forms of the Hymenoptera, Lepidoptera and Diptera, as the type of the cruciform larva, etc. * The larvæ of the earliest insects were probably leptiform, and the cruciform condition is consequently an acquired one, as suggested by Fritz Müller."
The evolution from scarcity to moderation and from moderation to plenty has led to the resources of husbandry. The animals forestalled us this path of progress. The ancestors of the Philanthus, in the remote ages of the lacustrian tertiary formations, lived by prey in both the larval and the adult forms: they hunted for themselves as well as for the family.
In the end taxonomy had to be altered so as to conform with the fact of development, and the name Zoaea disappeared altogether as that of an independent genus, persisting only as a convenient term for an important larval stage in the development of crabs. These two kinds of study give us a knowledge of the animals now living.
There were other shadows that were no more than ghosts of shadows, cast by faint, diaphanous films of scum which scarcely achieved to blur the clear downpour of radiance, but were nevertheless perceived and appreciated by many of the delicate larval creatures which made a large part of the life of the pool.
