Olfactory responses to milkweed seed extracts in the milkweed bug
Journal of Insect Physiology, 1976Abstract Electrophysiological studies showed that milkweed seed extracts have compounds which are stimulating to the olfactory chemoreceptors of the adult milkweed bug, Oncopeltus fasciatus. Ethanol extracts were the most stimulatory. These compounds may function as feeding attractants or stimulants.

One of the biggest chores associated with rearing milkweed bugs (Hemiptera: Lygaeidae) on their natural diet of milkweed seeds is the annual collection of the seeds. This paper describes a machine which can be easily and cheaply made with shop facilities and which mechanically removes milkweed seeds from their pods.
