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
YCNH and…
Top Photo: Immature plumaged yellow-crowned night-heron pays visit to wetlands. Night-herons have been observed in our wetlands four, perhaps, five times. All but one of those birds was a yellow-crowned night-heron (YCNH), the other, a black-crowned night-heron (BCNH). Of the YCNHs, one of them arrived in May and spent most of the 2011 summer. The other birds were only seen briefly, for one or a few days each. As you might suspect, night-herons often hunt at night and sleep awayRead more
Final Nest Box Update 8.1.23
Top Photo: Eastern bluebird eggs. The bluebird nesting season here at the museum is officially over. There’s no activity in any of our six nest boxes. The table below is a total of all the birds fledged since 2012, when I first began monitoring the nest boxes. There were a total of 36 birds fledged this season. The best years for bluebirds were during the 2012, 2013, and 2014 seasons. Chickadees had their best years in 2013, 2018, and 2023,Read 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
Nest Box Update 7.25.23
Top Photo: Eastern bluebird eggs. We are now down to zero nest activity. ————————— The Cow Pasture nest which held five house wren nestlings last week has fledged them all. I could hear them in the woods behind the nest box as we checked in on them this morning. The remaining five nest boxes are empty. ——————————— I’m calling the season over. I’ll make one last trip around the nest box trail at the start of next week, but IRead 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
Nest Box Update 7.11.23 and 7.18.23
Top Photo: Eastern bluebird eggs. (This post covers two weeks of nest box inspections due to my absence) We have one active nest, the Cow Pasture. ————————— The Cow Pasture nest has what looks to be five house wren nestlings. The oversized bills on the birds give it away. (Thanks to Ranger Dakota and Volunteer Sammie for getting a photo of the nestlings last week – 7/11/23). Previously, there were six eggs in the nest but in both photos, fromRead more
Nest Box Update 7.4.23
Top Photo: Eastern bluebird eggs. We have one active nest, house wrens for a second brood at the Cow Pasture. ————————— The Cow Pasture nest, as it did last week, has six house wren eggs. I was expecting nestlings. I didn’t see or hear an adult in the area which makes me wonder whether this nest has been abandoned. Though, six eggs is a large investment for these birds to quit. We’ll see what happens next week. The Explore theRead more
