The larva? had been found on Aconitum napellus, but the Lizards were unharmed by the poisonous food in the larval digestive canal. Eaten greedily by Hyla At once attacked by L. muralis, the larva being immediately detected, although rolled up and motionless. Nevertheless the Lizard evidently much disliked it, and after being severely bitten, it was rejected ; others tasted the larva with the same result. J. Jenner Weir. Eaten by Lizards... Eaten by Zootoca vivipara. The " larvas only which ventured beyond the protection of the web were eaten" by birds. The birds " appear very much to dislike the web sticking to their beaks." Other observers. A. Weismann.- Devoured by Lacerta viridis. A . C Butler.-Eaten by L. viridis. Larvse of this genus and of Hadena eaten by many birds (e. g., Eobins). Bearing upon Wallace's converse suggestion. Support. Support. Support, as with last species. Strong support, from the special character of the concealment. Support. Support. At first sight a most startling difficulty. Yet it was evident, from the behaviour of the Lizards, that they fully expected the larva to be palatable ; in itself a strong confirmation of the suggestion that nearly all such larvae are palatable. Support. Being defended by the web there is no necessity for a specially perfect form of protective resemblance. |
