Strange thing, nobody ever says "as green as a green bottle fly."
'Cept maybe an entomologist.
You've heard:
- As green as an emerald
- As green as a lizard
- As green as a gourd
- As green as grass
- As green as bottled glass
- As green as it gets
But as "green as a bottle fly" (or blow fly in the family Calliphoridae)?
No. Most people cringe at the very sound. They associate green bottle flies with their larvae, aka maggots, which eat rotting flesh. These insects lay their eggs in cadaver tissue. At crime scenes, forensic entomologists can determine the time of death by examining the developmental stage of the larvae.
And, of course, maggots are used medically in maggot therapy (to consume dead tissue around live tissue).
Then there's Maggot Art, coined by a former UC Davis entomology major, Rebecca O'Flaherty. At the annual UC Davis Picnic Day, children visiting Briggs Hall (home of the UC Davis Department of Entomology and Nematology) engage in Maggot Art, picking up a maggot with forceps, dipping it into non-toxic, water-based paint, and then letting it crawl on a white sheet of paper! Voila! Maggot Art, suitable for framing! (See Bug Squad, "Me and My Maggot." Some of the young artists get quite attached to the maggots and ask their parents if they can take them home. Of course, the answer is "Yes!" (Not!) Want to try Maggot Art? Mark your calendar for April 22, 2017 when the 103rd annual UC Davis Picnic Day takes place.
Green bottle flies can also be beautiful. Have you ever seen an emerald green bottle fly sipping nectar from a red flower, such as Lantana? When the light is just right, this little insect can make you say "Wow!"
Plus, it's a pollinator. It gets a little recognition, but not much, during National Pollinator Week.

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.

It apparently originated during World War II. Remember the 1942 film, "The Flying Tigers," starring John Wayne as Capt. Jim Gordon?
John Wayne, aka Jim Gordon, asks a Rangoon hotel clerk about a missing plane: "Any word on that flight yet?"
The hotel clerk replies that Japanese aircraft attacked the plane, but "She's coming in on one wing and a prayer."
Then there's the 1944 film, "Wing and a Prayer," about "the heroic crew of an American carrier in the desperate early days of World War II in the Pacific theater" (Wikipedia).
Fast forward to today, but this time with migratory monarchs. It seems that, they, too, fly on a "a wing and a prayer."
Over the last two months, we've seen dozens of migratory monarchs-often four or five at a time--stop for flight fuel in our 600-square foot pollinator garden in Vacaville, Calif. Many arrive in poor condition, their wings gouged, shredded and tattered. Still, they manage to sip nectar from Mexican sunflowers (Tithonia), butterfly bush (Buddleia) and Lantana, and continue their hazardous journey.
Imagine how incredibly difficult it is for these tiny, fluttering insects to weather the elements, not to mention evading birds, praying mantids and other predators.
Not all will make it. But look for some to arrive in the overwintering spots along coastal California "on a wing and a prayer."

How's your front yard looking?
A little bit brown due to the drought? Thinking of replacing some of your plants with drought-tolerant ones? And hoping to attract some bees, butterflies and other wildlife?
You're in luck. The UC Davis Arboretum is planning its next public plant sale this Saturday, Oct. 11. The theme is, appropriately enough, "The New Front Yard."
The plant sale will take place in the UC Davis Arboretum Teaching Nursery on Garrod Drive. It's open to members only from 9 to 11 a.m. (but if you're not a member, you can join at the door), and it's open to the general public from 11 a.m. to 1 p.m.
UC Davis Arboretum officials point out that many homeowners want to replace "high-water use plants with low-water alternatives" and they're going to help you. "We are going to have the area's largest selection of attractive, drought-tolerant, easy-care, region-appropriate plants including lots of California natives and Arboretum All-Stars."
They've published a list of some "attractive, region-appropriate plants that save water and support wildlife," complete with botanical names and photos. (Download PDF)
They include California buckeye, manzanitas, California pipevine, narrow leaf milkweed, Frikart's aster, Caliifornia aster, coyote brush, creeping Oregon grape, Blonde ambition blue grama grass, western spicebush, concha Ceanothus, Ray Hartman's California lilac, western red bud, Island mountain mahogany, California fuchsia, California buckwheat, St. Catherine's lace, coast silktassel, salt heliotrope, toyon, purple lantana, Goodwin Creek lavender, cape weed, monkey flower, deergrass, Hopley's purple oregano, Santa Margarita foothill penstemon, hollyleaf cherry, blue oak, California coffeeberry, pink chaparral currant, flowering currant, Santa Catalina Island currant, white sage, Cleveland sage, autumn sage, Santa Barbara sage, Cascade Creek California goldenrod, alkali sacaton, yellow autumn crocus and Roger's red grape.
Those are just a few of the plants they're offering for the plant sale.
Ah, so many choices, so little space. And one of the best parts? The bees and butterflies and other pollinators they attract.

There's something about seeing a butterfly that makes your eyes light up, your smile widen, and your feet feel like skipping.
Nature's joy.
So when I was over at Kaiser Permanente in Vacaville last Tuesday, I rejoiced at seeing a magnificent anise swallowtail, Papilo zelicaon, fluttering around the lantana flower beds near the entrance.
The butterfly flashed its brilliant yellow and black colors in the morning sun as it glided around the flower bed, touching down occasionally for a sip of nectar.
Such a beautiful, awe-inspiring, glorious creature.
So I did what comes naturally—I pulled the camera out of my bag—somewhat like pulling the rabbit out of a hat because you never know what kind of magic may--or may not--happen. Assuming my best "non-predator posture," I slowly trailed it from blossom to blossom, dropping down to capture its image.
It was then that I noticed a woman sitting on a nearby bench, smiling, as she watched the photographer follow the butterfly.
“I love butterflies," she said. "I collect butterflies—jewelry. I would never collect the real thing. They're too beautiful.”
“Me, either,” I said. “I try not to disturb them—I just photograph them.”
Half an hour later, I returned to the area only to observe a stricken look on the woman's face.
“You have the last photo of that beautiful butterfly," she said. "A bird ate it."
And right in front of the managed health care facility.
