These are toxic due to their secondary metabolites including diterpene esters with numerous harmful biological activities, preventing their use by most herbivores. Extracts of frass from &lt;em&gt;H. euphorbiae&lt;/em&gt; and of its main larval food plant in Central Europe, the cypress spurge (&lt;em&gt;Euphorbia cyparissias&lt;/em&gt; L.), were analyzed via liquid chromatography using a triple-quadrupole (MS/MS) and a high-resolution&amp;ndash;quadrupole time-of-flight mass spectrometer (QTOF-MS). We report for the first time the finding of the tigliane (phorbol ester) phorbol-13-acetate and two 12-O-tetradecanoylphorbol-13-acetate (TPA) isomers of unknown structure (compounds 2 and 3) in &lt;em&gt;E. cyparissias&lt;/em&gt;. Our data support the assignment of these two compounds as tiglianes and are therefore referred to by us as &amp;ldquo;putative tiglianes&amp;rdquo;. Additionally, the distribution of the three reported compounds within the plant parts (leaves, stem and root) was analyzed to gain first insights into the metabolite conditions &lt;em&gt;H. euphorbiae&lt;/em&gt; copes with in nature. Phorbol-13-acetate was detected in the plant&amp;rsquo;s root only, while the other compounds were observed in all three plant parts, although in different distributions. Moreover, our results indicate that the occurrence of compound 3 rises upon larval feeding. Finally, the presence of the plant-derived putative tiglianes in frass from &lt;em&gt;E. cyparissias&lt;/em&gt; leaves feeding larvae is confirmed, corroborating the close plant&amp;ndash;herbivore interaction.&amp;quot;&lt;/p&gt;
