Top Photo: Banded sphinx moth caterpillar barely hanging on. Following the night of our first frost of the season I ventured out to the Floating Walkway in our wetlands to see if I could find a banded sphinx moth caterpillar that had been seen the day before. I was interested in learning about their behavior in regard to pupation, where, when and how they go about that process. The caterpillar was still there. It was, however, only hanging on byRead more

Another Sphinx?
Top Photo: Fourth instar banded sphinx moth caterpillar (photo – Ranger Lauren). What at first appeared to be a new species of sphinx moth caterpillar on the quickly fading wingleaf primrose-willow (Ludwigia decurrens) in our wetlands here at the museum, turned out to be another of many banded sphinx moths (Eumorpha fasciatus) seen this year. It was a 4th instar caterpillar, and so, different in pattern than the preceding 3 stages and the following and final 5th stage of caterpillarRead more
Adeyha
Top Photo: Adeyha’s shaky first steps into our Red Wolf Enclosure. Born in May of 2014 our new red wolf is a nine year old male. He arrived onsite from Naibi Zoo in Coal Valley, IL. to his new home here at the museum Tuesday night October 24 and was placed in the kennel area of our Red Wolf Enclosure. The gate to the kennel was opened Thursday morning and out he came. He spent most of the morning cautiouslyRead more
Seeds, Leaves, Two Volunteers, and a Flower
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
Caterpillars Galore, a Mushroom, and a Broken Heart
Top Photo: Virginia tiger moth caterpillar. For those who appreciate lepidopteran larvae, last week was caterpillar paradise. Collectively, we rangers found several Virginia tiger moth caterpillars (above and below), a dozen banded sphinx moth caterpillars, a couple of smartweed or smeared dagger moth caterpillars, a southern flannel moth caterpillar and a camouflaged looper. And, thanks to Landscape Tech Jenn we got to see a couple of cauliflower mushrooms. Virginia tiger moth (Spilosoma virginica), also known as yellow bear caterpillar, canRead 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
