Top Photo: Tiny seeds from pod of wingleaf primrose-willow in wetlands. Wingleaf primrose-willow (Ludwigia decurrens) is sometimes called seedbox because of its seed pod shape, square in cross section. Other names include, wingstem water primrose, willow primrose, upright primrose-willow. The alternate leaves of Ludwigia decurrens are “decurrent” – the leaf base extends down the plant’s stem as “wings.” This herb grows in wet or marshy areas, and is sometimes aquatic. Fragments of the plant will root in a day or twoRead more

Borers, Bees, Pods, Sunflowers, and Nest Box Maintenance
Top Photo: Locust borer on goldenrod. Each year as goldenrod puts forth flowers, I expect to see locust borers actively feeding on nectar from the bright yellow florets. The beetles are rather well camouflaged among the flowers and not always easy to find. In late summer through fall, the adult beetles lay eggs in cracks of black locust bark. The hatching larvae burrow into the inner bark to overwinter. The warm temperatures of spring bring about renewed larval activity, andRead more
Another Stinkhorn, 4 Butterflies, 2 Wasps, Young Anoles, a Groundhog, and a Blooming Redbud
Top Photo: Devil’s stinkhorn. The spreading of mulch is a common chore here at the museum. What with new plants going in, exhibits being installed or altered and multiple other projects going on, mulch is a common sight. Following the mulch, sometimes months later, comes fungus. Various mushrooms rise up out of the decaying organic material in the mulch. Pictured, we have what looks like devil’s stinkhorn (Phallus rubicundus) which is not a North American species. It’s similar to nativeRead more
Some Insects To Keep An Eye Out For
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
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
Spittlebug
Top Photo: Spittle on muscadine grape stem. The white gooey substance on the grape stem, above and below, may at first appear to be spit or saliva, it’s not. The viscous, sticky stuff on the stem is called spittle. It’s created by spittlebug nymphs, insects. After hatching from eggs laid in or on the grape vine, nymphal spittle bugs begin feeding, sucking juices from the plant. This goes through the insect’s body and is forced out of the anus. MixedRead more
Tussocks and Other Summer Treats
Top Photo: Sycamore tussock moth caterpillar crawls along railing. If there are sycamore trees in the area you’re likely to run into one or more of these fuzzy, tufted caterpillars. The adult sycamore tussock moth has tan wings crossed with slightly darker bands on translucent membranes. More common and widespread than the sycamore tussock moth caterpillar, is the white-marked tussock moth caterpillar. It’s been reported munching on over 140 host plants including conifers. White-marked tussock moth’s adult form is aRead more
Spiny-backed Spider and More
Top Photo: Spiny-backed orb weaver (Gasteracantha cancriformis) Only about 1/2” wide, spiny-backed orb weavers are distinctive for their shape and pattern. The individual pictured is mostly white with black markings and red spikes. But, they may also be yellow or red with shades in between. The spines may be black. Some suggest the spines may deter predators such as birds or even subterranean-nesting, spider-seeking, solitary wasps. I doubt birds would be put off by the spikes. I must admit, though,Read more
