That honey is fatal to carnivorous larvae is a fact which teems with consequences. Several Hunting Wasps feed their families upon Bees. These include, to my knowledge, the Crowned Philanthus (P. coronatus, FAB.), who lines her burrows with big Halicti; the Robber Philanthus (P. raptor, LEP.), who chases all the smaller-sized Halicti, suited to her own dimensions, indifferently; the Ornate Cerceris (C. ornata, FAB.), another passionate lover of Halicti; and the Palarus (P. flavipes, FAB.), who, with a curious eclecticism, stacks in her cells the greater part of the Hymenopteron clan that does not exceed her powers. What do these four huntresses and the others of similar habits do with their victims whose crops are more or less swollen with honey? They must follow the example of the Bee-eating Philanthus and make them disgorge, lest their family perish of a honeyed diet; they must manipulate the dead Bee, squeeze her and drain her dry. Everything goes to show it. I leave it to the future to display these dazzling proofs of my doctrine in their proper light. CHAPTER 11. THE METHOD OF THE AMMOPHILAE. (For these Sand-wasps, cf. "The Hunting Wasps": chapters 13 and 18 to 20.--Translator's Note.) My readers may differ in appraising the comparative value of the trifling discoveries which entomology owes to my labours. The geologist, the recorder of forms, will prefer the hypermetamorphosis of the Oil-beetles (The chapter treating of this subject has not yet been translated into English and will appear in a later volume.--Translator's Note.), the development of the Anthrax (Cf. "The Life of the Fly": chapter 2.--Translator's Note.) or larval dimorphism; the embryogenist, searching into the mysteries of the egg, will have some esteem for my enquiries into the egg-laying habits of the Osmia (Cf. "Bramble-bees and Others": chapter 4.--Translator's Note.); the philosopher, racking his brain over the nature of instinct, will award the palm to the operations of the Hunting Wasps. I agree with the philosopher. Without hesitation, I would abandon all the rest of my entomological baggage for this discovery, which happens to be the earliest in date and that of which I have the fondest memories. Nowhere do I find a more brilliant, more lucid, more eloquent proof of the intuitive wisdom of instinct; nowhere does the theory of evolution suffer a more obstinate check.
