{108} He found that the lizards ate the so-called distasteful forms such as _Danais chrysippus_, _Euploea core_, _Acraea violae_, and _Papilio hector_, as readily as the presumably more palatable forms[57]. In captivity, too, they will take any butterfly as readily as another. Experiments by Finn[58] and by the writer[59] proved that they ate Danaids, Euploeas, and _Papilio aristolochiae_ without any hesitation so long as the insects were alive and moving. When, too, a mixture of different species, some with and some without warning coloration, was given to them all were eaten, nor was there any discrimination evidenced in the order in which they were taken. The lizard simply took the first that came within reach and went on until the whole lot was devoured, wings and all. Some experiments by Miss Pritchett on the American lizard _Sceleporus floridanus_ point to the same conclusion[60]. She found that it took without hesitation any butterfly offered to it including the presumably distasteful models _Danais archippus_ and _Papilio philenor_ (cf. pp. 45 and 49). On the other hand, another species of lizard with which Miss Pritchett experimented, _Gerrhonotus infernalis_, refused all the butterflies offered to it, though it fed freely on Orthopterous insects as well as on spiders and scorpions. It seems clear from these various observations and {109} experiments that certain lizards devour butterflies freely, but that they do not exercise any discrimination in the species which they attack. All are caught and devoured indiscriminately, so that in spite of the fact that such lizards are among the most serious enemies of butterflies we cannot suppose them to play any part in establishing a mimetic resemblance.
