This pigment has been isolated. The UV-visible spectra, the color changes, the reduction by dithionite, the polarity on SiO&lt;sub&gt;2&lt;/sub&gt; TLC, and the high molecular weight relate this pigment to an anthocyanidin derivative derived from the plant food. This result is discussed in connection with the presence of similar substances in plants of the family Apocynacea and in other moth species of the Sphingidae group, in which they play aposematic roles. As a hypothesis, it is suggested that the green pigment results from a reaction between &lt;i&gt;Nerium&lt;/i&gt; sp. anthocyanidins (plant food) and NH&lt;sub&gt;2&lt;/sub&gt; groups of basic constituents present in the animal.&amp;quot;&lt;/p&gt;
