Monarchs Lovin' the Lantana, One Sip at a Time

Nov 9, 2016

What amazing journeys!

For the last two months, migratory monarch butterflies have regularly stopped for flight fuel in our 600-square-foot  pollinator garden in Vacaville, Calif. to nectar on Mexican sunflower (Tithonia), butterfly bush (Buddleia) and Lantana.

At any given time--morning and afternoon throughout September and October--we'd see four and five in the garden. A veritable migratory corridor! A veritable visual feast!

Now it's November, and we haven't seen any for a week. They've probably already reached their destination--overwintering sites in the area, including Santa Cruz and Pacific Grove.

On Labor Day, we photographed a tagged one, part of the research project of David James, entomologist at Washington State University. (See Bug Squad blog;  WSU News story by Linda Seiford; and a Daily Evergreen piece by reporter Haley Donwerth on the Vacaville find. ABC, Channel 10, Sacramento, also covered "Why does this butterfly have a sticker on it?", interviewing butterfly expert Art Shapiro, UC Davis distinguished professor of evolution and ecology.

It's exciting to read the reports on the Monarchs in the Pacific Northwest Facebook page, as the tagged monarchs are photographed and recorded. Several recent entries:

  • Nov. 7: "Two new tag recoveries from California! Both are currently in the Lighthouse Field, Santa Cruz overwintering colony (currently numbering about 7000) and both were found by John Dayton. The tagged Monarch (shown on the page)  has flown at least 750 miles from Redmond, WA where it was reared and released on September 20 by Connie Grandberg. This is the first recovery of a Seattle-area Monarch in our program! There are now 4 PNW-tagged Monarchs residing at Lighthouse Field! We will provide information on the second new recovery once we get all the associated details."
  • Nov. 7: Our second new tag recovery from Santa Cruz! This one is remarkable in that it is almost obscured from view among the other butterflies. As luck would have it, the only bit of the tag showing for John Dayton's camera is the bit with the serial number! A6935, is a female, and she was reared in Brookings in southern Oregon by Andrea Christensen and released by her at nearby Redwood Bar along the Chetco River on August 25. Santa Cruz will be Ms A6935's winter home and who knows where she will go next spring? Many thanks to Andrea and John for making this recovery possible!"
  • Nov. 2: "Today we proudly announce the 9th long distance tagged Monarch recovery of this season so far! A female Monarch tag B2174 was found on November 1 at Morro Bay State Beach by Regena Orr a biologist with CA State Parks. B2174 was among about 350 clustering Monarchs and has travelled an estimated 792 miles since September 8 when it was released in Yakima, Washington! This Monarch was reared by Cindy Dunbar as part of a rearing program between PNW Monarchs and Cowiche Canyon Conservancy. 152 monarchs were reared by the 14 members of this group in 2016 and this is the first recovery for the group Congratulations! This Monarch now holds the record of the longest distance traveled by a Yakima-released Monarch. The photo shows a silhouetted group of Monarchs at Morro Bay in 2015."

Stay tuned. And stay focused with your camera! You might see a tagged one at an overwintering site.
