|This is a lady Crane Fly. Picture taken 11 Jun 2008, resting on a leaf
of the Virginia Creeper vine. It is about 3/4" long, not counting the long legs.
|Two years later, almost to the day, here is a pair of
Crane flies doing their thing on the same Virginia Creeper vine, at just about the same
location in the vine. Picture taken 10 June 2010.
|This one has some similarities to a Crane Fly, mostly the long legs. It was found on 29 August 2009 early in the morning, when the illumination was just one small CF bulb. I came back later after the sun was up, but the fly had departed.|
| House Fly, picture taken 13 July 2008 in Colorado Springs.
The second picture was taken 18 June 2008, in Colorado Springs,
and shows eggs that have been laid in the dog's food dish. The eggs are a little
over 1 mm in length. The larvae (maggots) will hatch in less than a day, and grow to
a length of 3 - 9 mm in length. Later, the maggot will transform into pupae, and
adult flies will emerge from the pupae. A female fly will be ready for mating within
about 36 hours.
|A pair of flies, identification not done yet. Seen at the Fountain Creek Nature Center on 28 June 2009.|
|A Blow-fly, AKA Blow Fly or Blowfly.
More specically, it is probably a Green Bottle Fly.
Picture taken 12 July 2008 in
Colorado Spring, Colorado. The back is uniformly green; my camera made it look two-toned.
The identification was made by the folks at www.bugguide.net.
|A Horse Fly. This was a large male, between 3/4" and 1" not counting legs.
The picture was taken in El Paso County, Colorado on 15 July 2008. There are about 350 species
of Horseflies in North America, and about 3,000 world wide. This species is the Western Horse Fly, Tanabus puncitifer.
|Another Western Horse Fly, this one at the Fountain Creek Nature Center on August 3, 2016.
|This is a Bee Fly. This family of flies are called Bee Flies because by evolution,
they have taken on the appearance of a bee, and hence avoid being eaten by predators that avoid bees.
They do not have stingers.
It is about 3/8" long, at the Fountain Creek Nature Center on 20 September 2008.
There are several species in the genus Poecilanthrax, but maybe this is willistonii.
|Another Bee fly, this one in the Genus Anastoechus.
Species not determined yet.
It is about 1/4" long, at the Fountain Creek Nature Center on 20 September 2008.

|More Bee flies, these found on 2 October 2009 in a Marigold patch in Colorado Springs, CO. Identified as flies since they have two wings, not four, and as Bee Flies since they look like bees. Further identification has not been made yet.|| |
| This Sinuous Bee Fly was indentified by Ron Hemberger on
This was found on 17 July 2013 in Colorado Springs, CO.
Kingdom Animalia (Animals)
|According to the folks on
www.bugguide.net, this is a Tachinid Fly, a member of the Tachinidae family.
It was found in Cripple Creek, Teller Co. CO on 3 July 2012 attracted to the thistle.
Identification down to genus and species is by me, based on photos on the internet.
|Mosquito. This photo was taken on 20 August 2008 at the Fountain Creek Nature Center,
from one of their ponds. It is a larva, about 1.5mm long, so it barely fit in the field of view
of my microscope at x100 magnification. There are about 40 genera, and over 150 species in the United
The larva hatched from an egg, and in turn will transform into a pupa, which in turn will result in an adult mosquito, which in turn will lay more eggs. A male mosquito will live only about a week, while the female mosquito, the only one that bites, will live about a month.
|This is the larva of some variety of Mosquito. It is about 3mm in length.
When I first saw it, I thought it was a mosquito larva, since it is about the same size
and had the same jerky motions.
But it lacks the air tube at the tail end that is visible in the photo above.
I am still researching this, but I believe that at some stages of development,
the air tube drops off.
It came from the Mosquito pond at the Fountain Creek Nature center on 25 July 2009. I used a Canon DSLR camera with the lens on a bellows extension for close-up work.
| This is a Midge fly, found on 7 June 2011 at Eleven Mile Lake, Park co., CO.
This is only one of many hundreds of thousands, if not millions that were flying around
that day. I do not have an identification down to the genus and species level.
Body length about 1cm. Common names are Midge, Gnat, Cranefly, Snow fly, Blood Worm,
Deer Fly, Black Fly, and Mosquito.
The second and third pictures are some that rode along with me on my boat on Eleven Mile Lake, 17 June 2011.
| These are Midge flies, found on 8 April 2012 in Colorado
Springs. Many of them were in my gazebo, trying to escape from the netting, late in the day.
The experts on
www.bugguide.net say that this is a male in the Chironomini tribe. An identification down to
genus and species would need a more detailed examination.
Body length about 5mm.
|This would be the larva of some fly. It was found at the Fountain Creek Nature Center on July 18, 2014. It was crawling or digging in the gravel of one of the hiking trails near one of the lakes. I thought it was a centipede until I noticed that all the legs were at one end. My camera did not focus precisely. It was about 1" long. Identification has not been made yet.|
