As long as you send images to me (and I hope it will be for forever), I shall continue to share them with my readership. My purpose for posting these images is to remind all of us of the grandeur of the natural world and that there is a world out there that is populated by millions of unique species. We are a part of this world whether we like it or not: we have a choice to either preserve these species or to destroy them in search of short-term monetary gains. But if we decide to destroy these other life forms, the least we can do is to know…

Totally cool paper in the last Science:

Regulation of Drosophila lifespan by olfaction and food-derived odors:
Smell is an ancient sensory system present in organisms from bacteria to humans. In the nematode Caeonorhabditis elegans, gustatory and olfactory neurons regulate aging and longevity. Using the fruit fly, Drosophila melanogaster, we show that exposure to nutrient-derived odorants can modulate lifespan and partially reverse the longevity-extending effects of dietary…

Woodland Skipper, Poanes melanae,
puddling at a seep in the Deschutes National Forest
on 18 July 2006.
Skippers are ubiquitous. This is a fairly small, compact
butterfly. When a large number are nectaring in a
concentrated fashion, one can hear the fast flutter
of their wings.

Dogday Harvestfly cicada. Tibicen canicularis
Found along the K&P Trail near Snow Road Station in eastern Ontario.

I love cicadas because they are so interesting and also because they remind me of Tokyo, Japan, where I first was introduced to them.
Happy Holidays to everyone.

Soldier Fly, Hermetia illucens.
One does not ordinarily think of a soldier fly as a pollinator, but this one, with some green
camoflauge, was sipping from a Philadelphia fleabane last year at Anahuac NWR, Texas
on 2 April 2005.

clock | December 14, 2006Identification Of Carbon Dioxide Receptors In Insects May Help Fight Infectious Disease:
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. Now, reporting in today's advance online publication in Nature, Leslie Vosshall's laboratory at Rockefeller University has identified the two molecular receptors in fruit flies that help these insects detect carbon dioxide. The findings could…
