MODIFIED EXUDATES. “In some species, pheromones are derived or modified from other sources: tiger moth caterpillars sequester poisons from their milkweed food plants and as adults, males metabolise some of these pyrrolizidine alkaloid poisons into volatile pheromones, attractive to females and indicative of the size of poison gift they will transfer along with sperm at mating. Tropical euglossine orchid bee males collect their pheromones as a ‘take-away’ from a species-specific set of orchid flowers.”
