Dog Agility

September 29th, 2012

I spent the day photographing at the Australian Shepherd Club of Mid-America's All Breed Agility Trials at the Columbia Canine Sports Center. Here's a portrait of a puppy. More images will be posted as soon as I can sort through thousands of images.

Brown Recluse Spiders

September 25th, 2012

I've been finding brown recluse spiders in our house for the past year. Here is one in a kitchen drawer.

The University of California - Riverside has a great resource for finding out more about brown recluse spiders, including "How to Identify and Misidentify a Brown Recluse Spider" and information on brown recluse spider bites from a Missouri physician who specialized in brown recluse bites. The American Medical Association has an article reporting that most brown recluse spider bites diagnosed by a physician are actually something else: "Convenient Culprit: Myths Surround the Brown Recluse Spider."

Three Creeks Conservation Area

April 11th, 2012

A blooming Blackhaw tree (Viburnum) near the Devil's Ice Box parking lot started off the evening wildflower walk on Wednesday, April 11th, at Rock Bridge Memorial State Park. We soon left Rock Bridge for Three Creeks Conservation Area several miles away. Normally we'd have gone there for bluebells (Mertensia virginica) but with everything blooming early this year and the wildflower walks starting a week later than some years, they had already finished blooming.

There were Wild Geraniums (Geranium maculatum, May apples (Podophyllum peltatum), Blue-eyed Mary (Collinsia verna), Wild Sweet William (Phlox divaricata), Columbine (Aquilegia canadensis), Dogwood (cornus), Wild Ginger (Asarum canadense), Bellwort (Uvularia grandiflora), Yellow Rocket (Barbarea vulgaris), Jack-in-the-Pulpit (Arisaema triphyllum), False Dandelion (Krigia biflora), and a few others.
