Imago of Sesia fuciformis. Imago of Porthesia auriflua. Method by which rendered more or less conspicuous. Black, with yellow bands; contained " in a very slight and perfectly transparent cocoon " {Newman). Blackish green and red. Rests very conspicuously on flowers &c. ; flight not rapid, and by day. So abundant locally as to be almost gregarious. The bright colours are well seen at rest and in flight; very sluggish and easily caught ; often feigns death when captured. Wings transparent, with brown margin; body various shades of brown. Flight by day very rapid, and insect seldom seen at rest. Its claim here depends on its somewhat Hymenopter-ous appearance: the closely allied S.bombyliformis "resembles the male of the Humble-Bee {Bombus hor-torum)" {Wallace). Almost all the surface, seen at rest, is white; there are also a few small black patches on the fore wings, and the body ends posteriorly in a conspicuous yellow tuft. Flight weak in the evening, when the Moth is very conspicuous, appearing white ; at rest it is also extremely conspicuous. Unpleasant attribute, real or suggested, in mimetic forms. ? Taste or smell. Proof lies in what follows. ? Taste or smell. Proof lies in what follows. The suggestion of a sting, according to some authorities. There may be an unpleasant taste or smell, but there is at present no experimental proof of this. Results of J. Jenner Weir. " Unwillingly eaten:" Jenner Weir thinks because the birds in confinement get fewer insects than when wild, and so will eat forms which they would reject if well supplied with this food. A. G. Butler. Always refused by L. viridis after having been seized. A single imago eaten by the Lizards. . _______.-- |
