On her arm is a Cordulegaster diadema, aka Apache spiketail, and it's beautiful.
Anna, who didn't follow her father's footsteps into the field of entomology, instead has a dragonfly within arm's reach.
Anna, employed at Deluxe Studios (remotely), and her researcher father recently attended an insect-drawing class at the Bohart Museum of Entomology open house, "An Evening at the Museum." The class, taught by Professor Miguel Angel Miranda of the University of the Balearic Islands, Spain, a participant in the newly concluded 10th International Dipterology Congress in Reno, drew such comments as "So much fun!"
No tattoo for Rosser?
"Nope," said Rosser. "No tattoos on me. Just over 50,000 preserved dried Odonata specimens--over 3000 species--from all over the world here at home in Sacramento."
Three thousand different species...that's nearly half of the world's 6000 described species of dragonflies.
Rosser served as a senior biologist/entomologist for Los Angeles County from 1984 to 2004 before becoming a senior insect biosystematist with the CDFA Plant Pest Diagnostics Branch, Sacramento, where he identified orthopteroid, heteropteroid, other groups of invertebrates including mollusks. He currently enjoys working on Odonata at his home in Sacramento.
One of them is C. diadema, commonly known as the Apache spiketail ("spiketail" refers to the female's prominent ovipoistor). The adult is usually 74-88 millimeters long. "It ranges from southwestern United States to Mexico and Costa Rica," according to Wikipedia, which notes: "The back of the head is yellow to brown with yellow to black hairs, though some have been reported with a black head with white hairs. The first proximal segment of the legs are yellow. The thorax has two lateral stripes with a yellow stripe between them."
The Bohart Museum featured Garrison and his work at its November 2022 open house on dragonflies. He displayed “the largest dragonfly in the world," Petalura ingentissima, found in Queensland, Australia. Its wingspan can measure 160 mm. Among his other specimens: some of the world's smallest dragonflies, including Nannothemis bella, Perithemis tenera (both eastern United States) and Nannophya phymaea (Singapore).
Anna isn't the only one in the family who has dragonflies within an arm's reach!
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of nearly eight million specimens, including 469 different species of dragonflies. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus., it is open to the public (summer hours) on Tuesdays from 2 to 5 p.m. Admission is free.

That's what Professor Miguel Angel Miranda of the University of the Balearic Islands (UBI), Spain, asked participants in his insect-drawing workshops on Saturday night, July 22 at the Bohart Museum of Entomology open house.
Miranda, newly returned from the 10th International Dipterology Congress, held July 16-21, in Reno, volunteered to demonstrate "how to draw a bug" at the Bohart open house. The four-hour event, billed as "An Evening at the Museum," featured displays of moths (National Moth Week) and flies (Dipertology Congress).
The half-hour art workshops took place in the Museum of Wildlife and Fish Biology classroom, adjacent to the Bohart headquarters in the Academic Surge Building.
First, the professor asked the participants what insects they like, and what they would like to draw.
"Centipedes!" a man said.
"That's not an insect," Miranda jovially replied. "What do you like about centipedes?"
Miranda turned to the other participants. "What other insects do you like?"
"Spiders!" a woman said. Miranda smiled, and agreed that spiders are cool, but "That's not an insect. What do you like about spiders?"
"The fangs," the woman answered.
The next response: "Dragonflies."
"What do you like about dragonflies?"
"The wings!"
Miranda, who joined the UBI faculty in 1995, is a zoologist, entomologist and noted insect illustrator. He currently teaches zoology, parasitology, and biotechnology applied for pest control. He is a member of UBI's Applied Zoology and Animal Conservation Research Group or ZAP. He served as the editor and cartoonist of the fanzine Plomi Corcat from 1991 to 1992. He curated the exhibition "Comic and Science" at the 2021 Comic Nostrum International Festival.
Miranda began his scientific career studying parasitoids of the pine processionary (Thaumetopoea pityocampa), a moth species that causes economic damage to coniferous forests. He researched Mediterranean fruit flies for his doctorate (1991). He has also researched tobacco aphids, scale insects of citrus, termites, ticks, sandflies and mosquitoes, including the Asian tiger mosquito Aedes albopictus. He has conducted extensive scientific work in the study of other insects of economic importance, including Hymenoptera parasitoids of plant pests, the red palm weevil (Rhynchophorus ferrugineus); parasites of bees, such as Varroa destructor; and the parasite Oestrus ovis. He writes a blog and posts Tweets.
"That class was so much fun!" said participant Nancy Ruiz, who added humor to the class by sketching a fly swatter and a fly.
