Robber Flies (mating pair)

September 2, 2018

A mating pair of Red-footed Cannibalflies (Promachus rufipes), a species of robber fly (Family Asilidae), was spotted during a photowalk along Deephole Point Road at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

There’s an obvious difference in the appearance of male and female Red-footed Cannibalflies: the male’s abdomen is “tiger-striped” for its entire length; the female’s abdomen is two-thirds tiger-striped, one-third black. Therefore, the male is shown on the upper-right in the following photo; the female on the lower-left.

More predator/prey at Occoquan Bay

August 29, 2018

“Eat or be eaten” is perhaps the most fundamental law of nature. Predator-prey relationships can change suddenly: one minute a predator, such as a damselfly, is hunting for its next meal; next minute the damselfly becomes the prey and is a meal for another predator, such as a spider, elsewhere in the food web.

23 AUG 2018 | OBNWR | Black and Yellow Argiope (plus prey)

A Black and Yellow Argiope (Argiope aurantia) was spotted during a photowalk along Deephole Point Road at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. A damselfly, possibly a Big Bluet (Enallagma durum), was trapped in the spider web.

Life and death at Occoquan Bay

August 27, 2018

An Osprey (Pandion haliaetus) was spotted perched on a dead tree limb overhanging Fox Road at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. This individual, possibly a male, is shown with a fish in its talons.

The fish appears to be an unknown species of goldfish. Did you notice the drop of blood in the preceding photo?

A Blue Dasher dragonfly (Pachydiplax longipennis) was spotted during a photowalk at Occoquan Regional Park, Fairfax County, Virginia USA. This individual is a female, as indicated by her coloration and terminal appendages.

This camera-shy girl was hiding her face from me behind the thin veil of her left forewing.

Wild Turkey (“record” shots)

August 19, 2018

Several Wild Turkey (Meleagris gallopavo) were spotted along the edge of the parking lot at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

Appearances to the contrary, the photos in this set were taken at quite a distance. Wary of my approach on foot, the turkeys did the turkey trot, moving from right-to-left until they were out of sight quickly.

Although I have seen signs of Wild Turkey at OBNWR, this is the first time I’ve seen actual birds. Not my best work, but hey, these “record” shots provide documentation of the sighting. With any luck, it won’t be the last time I see Wild Turkey at the refuge.
