It's a buggy new year! One of the fascinating things about beginning the new year is the Entomological Society of America's "World of Insects" calendar. Amazing images of insects (and one spider!) jump out at you.
One of my favorites is a black soldier fly, Hermetia illucens, an image captured by entomologist Jena Johnson of Athens, Ga. It's "Mr. October."
Johnson writes: "Soldier flies, like many other dipterans, have beautifully patterned eyes attributable to cornea filters that cause colorful metallic reflections. Adults of this species are black with dark wings and are 14-17 millimeters long. Although harmless, they are somewhat similar in appearance to mud dauber wasps, and they even mimic their movements. They also have two distinctive translucent spots on their first abdominal segments that make them appear to have narrow, wasplike waists. The larvae develop in decomposing organic matter and are considered to be beneficial in helping to reduce large amounts of animal manure and other biological wastes. Soldier fly larvae are a good protein food source for livestock, exotic pets and even humans. In the summer, adults are often attracted to fluorescent lights, which is how this one was lured in for a photograph in Athens, Georgia."
"The first time I looked into the eyepieces of a microscope to see the magnified beauty of an insect I knew I would spend my life involved somehow in learning more about this diverse and fascinating group of animals," Johnson told Bug Squad. "After working at the University of Florida for a couple of years I went on to earn a master's degree at Clemson University. I worked as an entomology laboratory technician at the University of Wisconsin and am currently at the University of Georgia. For many years I photographed insects with a 35mm film camera but when digital cameras became more affordable a few years ago, my passion for insect photography was reignited. I photograph insects for the pure joy it brings me. I live in Athens, Georgia with my husband Michael Strand, who is also an entomologist."
Michael Strand, by the way, will be the featured speaker April 8 in the series of noonhour seminars hosted by the UC Davis Department of Entomology and Nematology. (See list of seminar speakers.)
Jena Johnson, who is currently hotographing a variety of mosquito species emerging from pupae at the water's surface, is an alumnus of BugShot, an insect photography workshop. One of the instructors is noted insect photographer Alex Wild, who received his doctorate in entomology at the University of California, Davis, with professor/ant specialist Phil Ward. Wild, who has just accepted a position at the University of Texas, Austin, blogs about insects at myrmecos.net and about photography at Compound Eye, Scientific American. Wild's Oct. 26 2011 seminar at UC Davis on "How to Take Better Insect Photographs" is the department's most viewed seminar on UCTV.
It's obvious that people like bugs, and people enjoy capturing macro images of bugs!
A colorful image of a clown grasshopper by Francisco Lopez-Machada of Cali, Colombia, graces the cover of ESA's "World of Insects" calendar. It also appears as "Mr. August."

What a beauty.
But not nearly as striking as her male counterpart.
The flame skimmer dragonfly (Libellula saturata) owned a perch on a bamboo stake last Tuesday in residential Davis.
Davis resident Gary Zamzow, a dynamite insect photographer (especially bumble bees), pointed his Pentax camera at the insect, just inches away.
The dragonfly did not move.
“The female flame skimmers are not as intensely orange as the males are and they also have the expansions on the 7th abdominal tergite that you can see in your picture (below),” said senior museum entomologist Steve Heydon of the Bohart Museum of Entomology (http://bohart.ucdavis.edu/), University of California, Davis.
If you like dragonflies, you may want to purchase a dragonfly poster at the museum, located in Room 1124 of the Academic Surge building on Crocker Lane, or online at its gift shop. It features 18 species of dragonfies, ranging from the common whitetail and green darner to the Western river cruiser and the bison snaketail. And, of course the flame skimmer.
Entomology doctoral candidate Fran Keller designed the poster with images provided and donated to the museum by naturalist Greg Kareofelas of Davis.
