“Cicada-a-Raida Encore: the Cicadas are Back,” a Zoom Program

Periodical cicadas are rare. Of the roughly 3,400 cicada species on earth, only seven of these live underground as nymphs for 13 or 17 years and all are found in eastern North America. These true bugs are bland as nymphs burrowed underground but emerge as loud colorful adults with red eyes and golden wings. While the cicada’s emergence only happens periodically, it seems to be happening regularly in Tennessee. The fact is that there are 15 different populations called broods. In 2021, it was Brood X that thrilled us. Last year it was Brood XIX and this year it's Brood XI and each year it's in different locations.

Join the UT Arboretum Society via Zoom on Thursday, May 1, 7pm EDT as Michelle Campanis, education coordinator at the University of Tennessee Arboretum, and naturalist/author Stephen Lyn Bales present an overview of these bodacious bugs. The First Thursday Nature Supper Club presentation is hosted by the UT Arboretum Society each month. The class is free, but you must register to receive the Zoom link and recording. Register at www.utarboretumsociety.org under Programs.

Closed captions are available. Please contact Michelle at mcampani@utk.edu for any questions or registration issues.

The Smithsonian’s National Collection of Fishes X-rays represent more than 70 percent of the world’s fish specimens and is the largest and most diverse collection of its kind in the world. Although the X-rays featured in the national collection were made for research purposes, the strikingly elegant images demonstrate the natural union of science and art and are a visual retelling of the evolution of fish. X-Ray Vision: Fish Inside Out, an exhibition from the Smithsonian’s National Museum of Natural History and the Smithsonian Institution Traveling Exhibition Service (SITES), showcases these dramatic prints exposing the inner workings of the fish.

The exhibition features 32 black-and-white digital prints of different species of fish. Arranged in evolutionary sequence, these X-rays give a tour through the long stream of fish evolution. The X-rays have allowed Smithsonian and other scientists to study the skeleton of a fish without altering the specimen, making it easier for scientists to build a comprehensive picture of fish diversity.

The exhibition also includes specimens from the collections of the McClung Museum, the Etnier Ichthyological Collection, and the Vertebrate Osteology Collection to highlight research happening with fish specimens at the University of Tennessee.
