Top Photo: Tobacco hornworm on tomato plant. The tobacco hornworm, or Carolina sphinx, and tomato hornworm, or five-spotted hawk moth, both use nightshade as a food plant including tomato and tobacco plants. And, they’re both subjected to attack by a tiny parasitoid wasp called a braconid wasp. With the help of her ovipositor, the minuscule wasp lays eggs just under the skin of the caterpillar. The eggs hatch and the larvae begin eating the caterpillar from within. When the timeRead more

A New Caterpillar for the Photo Achives
Top Photo: Hummingbird moth caterpillar on viburnum. Just last week (8/19) I posted I was keeping an eye out for caterpillars of the hummingbird moth (Hemaris thysbe). I had spotted a moth the previous week laying eggs on a viburnum and wanted to get a photo of the caterpillar. I mentioned my observation to Richard Stickney of the Butterfly House crew and sure enough, he found one on the very viburnum I indicated (8/28). When seeing the caterpillar I wasRead more
Leaf-footed Encounter
Top Photo: Leaf-footed bug encounter on path. About one and a half weeks ago here on this blog, I mentioned an insect called a leaf-footed bug. I also posted a picture of the insect. At the time, I wasn’t sure of the identity of the insect beyond leaf-footed bug of which there are about 80 species in North America. Today, I came across two others of what appear to be the same species on the path in a closed (toRead more
Hummingbird Bird and Moth
Top Photo: Juvenile male ruby-throated hummingbird, rapidly beating wings blurred to near invisibility, hovers in front of trumpet vine’s tubular flowers. There are 16 species of hummingbird that breed in the United States. There’s only one species in the eastern states, ruby-throated hummingbird. If you see a hummingbird in North Carolina in summer, it’s a ruby-throated. From October into winter it’s most likely a different species that you see at your feeder, unless you’re on the Gulf Coast or ourRead more
New and Old Things Emerging
Top Photo: Tiny yellow flower of Mexican Sour Gherkin Cucumber. The fruit of the Mexican Sour Gherkin Cucumber is about an inch long. They look more like tiny watermelons but have the taste of a cucumber with a lemony tang. These vines grow in many locations throughout our campus, wherever they’re not supposed to grow. I intended to plant this vegetable in my own personal garden at home this year but was sidetracked by other matters. I’ll make sure toRead more
Bees, Leaf-footed Bugs, Luna Moths and More
Top Photo: Eastern tiger swallowtail nectars on coreopsis. Though they’re more obvious during spring when the white-faced males emerge to patrol areas around suitable nest sites for females, carpenter bees are active all season long. Spring, though, is when you’re most likely to run into one and perhaps be buzzed by the harmless males. Later in the summer they’re much less noticeable, but still around. You’ll probably see more females at this time of year and they’ll be more passiveRead more
What’s Out There
Top Photo: Mushrooms rise up through fresh mulch. The small, gilled mushrooms pictured here all emerged from mulch in Explore the Wild on the same day. The following day, they had disappeared. All that remained were a few stragglers. I’m not sure of the identity of these fungi. If you have an opinion, it’s welcomed. If you’re headed out to Earth Moves in Catch the Wind, you’ll probably run into a cloud of mist on your way. We’ve installed mistersRead more
Oakworms, Again.
TOP PHOTO: Early instar orange-striped oakworm caterpillars go to work on red oak leaves. It’s that time of year again when oakworms do their best to defoliate the red and willow oaks here at the museum. There may be thousands of these voracious moth larvae in the oak trees here at the museum but they never do as much damage as to harm the trees in any great manner. The trees seem to thrive regardless of the devouring hordes ofRead more
Out and About
Top Photo: Green heron perches on willow branch near water’s edge. Green herons are a fairly common sight in the wetlands during summer. They’ve nested at the museum more than a few times. I’ve previously mentioned in this blog the benefits for the naturalist who follows the eye of the bird. If you see a bird stare skyward it’s often worth your while to look up and see what the bird’s looking at. It may be a predator worthy ofRead more
