Top Photo: European hornet inspects bark of tree where hive is located. While you’re walking along the paths of our outdoor loop through the Dinosaur Trail, Explore the Wild and Catch the Wind keep an eye out for large yellow, black and brown wasps, European hornets. The wasps are large and intimidating but are considered non-aggressive. I agree. They’re social wasps. Here at the museum, all of the nests, or hives, of these vespids that I’ve seen were in aRead more

Turtles and Persimmons
Top Photo: Persimmon ripening on tree. It’s well known among catfish aficionados that persimmons will catch a bucketful of the opportunistic, gill breathing, bony fish. In the fall, if there’s a persimmon tree next to the pond there’s probably a catfish hovering nearby. I was surprised to learn this past week that besides catfish, aquatic turtles seek out persimmons. Not surprised so much by what they were eating (the persimmons) but by the length in which they’d go to doRead more
Soldierflies
Top Photo: Soldier fly larvae feeding in our wetland. I’m not sure of the species level identification but the larvae in the photos above and below seem to belong to the genus Stratiomys. They’re a genus of soldier fly which apparently lays eggs in the water. The adults are bee or wasp mimics and feed on nectar and pollen. The larvae that hatch from the eggs deposited by the adults eat detritus on the bottom of a shallow, muddy pondRead more
Early Fall Things To Discover
Top Photo: Yellowjacket picking over annual cicada. The yellowjacket in the images above and below is scavenging protein from a dead cicada on the path. Yellowjacket larvae back in the hive are fed protein in the form of whole insects or chunks of meat harvested from caterpillars and other larger animals, even from a picnicker’s ham sandwich. The yellowjackets take the meat back to the hive and feed it directly to larvae in cells within the hive after it’s beenRead more
Katydids
Top Photo: Angle-wing katydid (Microcentrum retinerve). Katydids belong to a group of insects known as Orthoptera which references the straight or parallel-sided aspect of their wings (ortho = straight, ptera = wing). This group includes grasshoppers, locusts, crickets, and katydids. You can usually distinguish katydids from the others by their longer antennae, though some types of crickets do indeed have long, thin sensory appendages. There are many kinds of katydids. The two mentioned here are an angle-wing katydid and aRead more
Banded Sphinx
Top Photo: Banded sphinx moth caterpillar preparing to chew on wingleaf primrose-willow in wetlands. Last September, I photographed a banded sphinx moth (Eumorpha fasciatus) caterpillar on an end-of-the-season wingleaf primrose-willow (Ludwigia decurrens) in the wetlands. There were only a hand-full of those plants in the wetlands at the time. This year, there are many. The larvae may be green-themed, red, black, or multi-colored. The genus name Eumorpha means “well formed” or “good shape” and the species name fasciatus refers toRead more

Late Season Hyla*
Top Photo: Juvenile green treefrogs (2) huddle safe and secure inside unfurling leaves during late summer (look carefully). Both young and adult green treefrogs rely heavily on their color and posture to “hide” themselves from possible predation. They often, though, squeeze down into tight nooks or recesses for added protection, as the juveniles in the above photo illustrate. We installed three artificial “hides” around the outdoor exhibits for our resident treefrogs. And, believe it or not, there are still frogsRead more
Mid-November
Top Photo: Two of six hooded mergansers circle wetlands. As in every year since I’ve been working at the museum, hooded mergansers have arrived in our wetlands by mid November. This year, six were spotted on the early date of November 9, though only two of them actually dropped in. Four birds were seen making a pass at the museum’s wetlands but continued on elsewhere. Since that day, they’ve been seen on the 12th and again on the 15th whenRead more
Oak and Niko
Top Photo: Oak (left) and Niko carefully watch members of the Animal Care crew in their enclosure during routine maintenance. Now that word is out about the new pair of red wolves having arrived at the museum, Niko and Oak, you may want to come have a look at them. Both wolves are still getting used to their enclosure and the rush of people stopping in or passing by the exhibit space. They’ve only been on-site a handful of daysRead more
