Your letter to the bugman: Dear Readers,
Daniel was out hiking near the Getty Museam in a Santa Monica Mountains Conservancy park when he pointed out the Narrow-Leaf Milkweed that was just beginning to bloom to his hiking partners Naeemah and Sharon. Some plants had numerous Blue Milkweed Beetles feeding on the leaves. According to BugGuide: “Larvae are obligate root feeders, and adults eat the leaves of larval host plants. Females are highly polyandrous, males engage in extended periods of post-copulatory mate guarding.”
Milkweed is a very popular plant with many pollinating insects including butterflies, bees and wasps. so many years ago we created a Milkweed Meadow tag for the complex ecosystem that is associated with milkweed.
Update: June 19, 2021 Mating Blue Milkweed Beetles
This weekend while hiking at the same location with Sharon and Melanie, Daniel spotted a solitary pair of mating Blue Milkweed Beetles. He managed to get one image before the presumably male Blue Milkweed Beetle dropped to the ground. Daniel felt somewhat guilty that his voyeurism led to coitus interruptus.
