Adult males mud-puddle and imbibe pyrrolizidine alkaloids from Heliotropium species, especially from the roots of dug-up plants.
At least two ships of the British Royal Navy have been named HMS Heliotrope after the genus of flower.
Heliotropine was discovered in 1869 by Fittig and Mielk who synthesised it and thus made the 'cherry pie' note of the heliotrope flower, for which it is named, available to perfumers for the first time - it was already in use in fragrances by the early 1880s.
