Why does finding yellow aphids on milkweeds pose a management challenge for Monarch butterfly conservation efforts?
Answer
Milkweeds serve as essential host plants for Monarch butterflies
The association between milkweed (*Asclepias* genus) and the Monarch butterfly creates a conservation conflict when yellow aphids are present. Milkweeds are critically important because they are the sole host plants upon which Monarch butterflies lay their eggs and the only food source for the resulting larvae (caterpillars). Therefore, managing the Oleander Aphid population that specializes in colonizing these plants must be approached carefully by gardeners focused on supporting pollinator health, as aggressive treatment against the aphids could inadvertently harm the essential life cycle stage of the Monarch.
