Article from Michigan Lakes and Streams newsletter Sept 1, 2022.
Editor's Note: This article focused on freshwater jellyfish originally appeared in this newsletter in the fall of 2019 - several reports of the appearance of the unique creature
in Michigan lakes over the course of the past couple of weeks have prompted us to re-publish for the sake of our many new subscribers.

Evoking expressions of surprise and delight, the initial experience of observing an only sporadically occurring swarm of undulating freshwater jellyfish gracefully propelling themselves through the late summer warm waters of your favorite lake always seems to be a joyful one. Commonly referred to as “peach blossom fish” in their native China, words such as fascinating, graceful, elegant, ephemeral, and mysterious are often deployed by authors in their attempt to aptly describe the exotic freshwater jellyfish species known as Craspedacusta sowerbii that only occasionally appears in Michigan’s inland lakes.
A native of China’s Upper Yangtze River basin, the exponentially increasing pace of international trade that has occurred over the course of the past century has inadvertently led to the fact that C. sowerbii has now been successfully introduced to every continent except Antarctica, and has become the most widely distributed freshwater jellyfish on earth. C. sowerbii and the nineteen other species of freshwater jellyfish in existence are classified as hydrozoans, a class of small colonial or solitary predatory animals that are related to sea anemones and corals. C. sowerbii belongs to the Cnidaria, a diverse phylum of hydrozoans that contains over 11,000 marine and freshwater species whose exotic physical appearance is primarily defined by a unique umbrella-like radial symmetry. Catalogued in England by naturalists in the 1880’s, C. sowerbii was first observed in Michigan waters in the 1930’s.
Representing an extremely delicate and highly elastic gelatinous creature that is intolerant of intense wave action and fast-moving waters, the freshwater jellyfish species known as C. sowerbii that inhabits Michigan waters is most often observed floating or gracefully swimming near the sunlit surface of ponds, reservoirs, quarries, and quiet wind-sheltered areas of inland lakes. Lacking a brain, heart, respiratory system, skeleton, and even blood, the relatively simple, delicate anatomy of C. sowerbii is comprised of a translucent bell-shaped outer layer known as the epidermis; a middle layer consisting of a thick, highly elastic, grayish-blue in color gelatinous substance that is referred to as the mesoglea; and, representing a simple digestive system that acts as both a stomach and intestine with just one opening that serves as both mouth and anus, an inner layer that is referred to as the gastrodermis which includes a crude stomach-like structure that is referred to as the manubrium. Circulation of nutrients within the ancient organism is facilitated by the existence of four radial canals that originate along the edges of the manubrium.
Freshwater jellyfish are known to possess a sense of smell, are able to detect light, and are capable of sensing and responding to near-by stimuli such as motion due to the existence of an elementary network of nerve cells that are widely distributed throughout their gelatinous body. The rim of their translucent bell-shaped epidermis is adorned with up to 400 relatively long tentacles that each possess thousands specialized cells called cnidocytes that are deployed by the organism to capture and pass prey consisting of tiny zooplankton to the opening of their gastrodermis. Drifting in the water column with its tentacles fully extended, jellyfish waits for suitable prey such as a tiny daphnia to come into contact with a tentacle. Once contact is made, nematocyst cells within the tentacle fire into the prey, injecting a tiny quantity of a powerful toxin that acts to paralyzes the animal, with the tentacle then acting to secure the prey by wrapping itself around the immobilized animal. It is important to note that stings by small freshwater jellyfish such as C. sowerbii produce only minor pain and often go unnoticed by swimmers due the miniscule amount of toxin that is injected as a result of contact with a tentacle. Mature C. sowerbii are capable of growing to a diameter of approximately 19 millimeters (penny-size), responding to the detection of stimuli such as near-by motion, however, the highly elastic gelatinous species is capable of instantaneously expanding its translucent epidermis to three times its normal diameter.
Beginning life as a tiny polyp attached to aquatic vegetation, rocks, or coarse woody debris, C. sowerbii and other species within the Cnidaria phylum possess a complex life cycle that allows them to expeditiously take advantage of the return of environmental conditions that are favorable to their survival and sustainability. In rare populations of C. sowerbii that possess both female and male individuals, the species is capable of achieving sustainability by alternating with each generation between reproducing sexually, with free floating sperm cells fertilizing eggs, and reproducing asexually by cloning themselves. Freshwater jellyfish are dimorphic, depending upon conditions, such as water temperature, the amount of light penetrating the surface, and/or food availability, freshwater jellyfish such as C. sowerbii are known to alternate between a polyp phase, a larval phase, and a relatively brief life in late summer as a sexually mature free-swimming male or female hydro-medusa. Freshwater jellyfish such as C. sowerbyi are known to spend much more time in existence as microscopic podocysts, frustules (larvae produced asexually by budding), planulae (larvae produced sexually by mature male and female hydromedusae), or as sessile polyps that attach themselves to stable submerged surfaces such as coarse woody debris and rocks. It is important to note that the vast majority of C. sowerbii colonies are comprised of all-male or all-female individuals, therefore rendering the species almost completely dependent upon asexual reproductive processes for long-term survival.
Intolerant of the cold-water temperatures that are present in northern temperate waters in late fall, winter, spring, and early summer, the most abundant colonies of mature hydro-medusa phase C. sowerbii are observed as late summer water temperatures reach their maximum in August and September. Most often observed floating or swimming near the surface on bright sunny days, the mature hydro-medusa phase of C. sowerbii comes to an end with the gradual emergence of cold-water temperatures. During the winter months when northern temperate water bodies are frozen over, C. sowerbii contracts and enters a long period of dormancy as resting bodies called podocysts. Once environmental conditions become favorable, they again enter the polyp phase that later in the summer leads to the formation of a mature hydro-medusa.

MDARD asks Michiganders to be on the lookout for spotted lanternfly, an invasive species threatening agriculture, natural resources
This story is from the Michigan Waterfront Alliance newsletter 08-01-22
The Michigan Department of Agriculture and Rural Development is asking for the public’s help by being on the lookout for spotted lanternfly, an invasive insect with the potential to seriously affect Michigan’s agriculture and natural resources. This insect feeds on more than 70 different plants including grapes, apples, hops and hardwood trees.
“Our agricultural and natural resources are part of Michigan’s identity, and spotted lanternfly has the potential to forever change that landscape,” said Robert Miller, MDARD’s invasive species prevention and response specialist within the Pesticide and Plant Pest Management Division. “With its ability to wreak havoc on grapes, apples, hops, stone fruits and more, this could be devastating to Michigan’s farmers and the state’s food and agriculture industry.”
First detected in the United States in 2014 in southeastern Pennsylvania, spotted lanternfly has been spreading rapidly across the northeastern states. To date, infestations have been confirmed in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Virginia and West Virginia.
Although live spotted lanternfly has not been detected in Michigan, MDARD and the United States Department of Agriculture have confirmed five cases of dead spotted lanternfly found in separate locations across the state. In these cases, the dead insects were found in packaging materials or objects shipped from states with known infestations.
Spotted lanternflies cannot fly long distances, but they lay eggs on nearly any surface like cars, trailers, firewood, outdoor furniture and more. Before leaving an infested area, MDARD is asking people to check vehicles, firewood and outdoor equipment for unwanted hitchhikers. Individuals and businesses receiving shipments from states known to have spotted lanternfly also should be on the lookout for adults or egg masses on goods and packing materials.
“With the current rate of spread, it is possible spotted lanternfly could reach Michigan at any time,” Miller added. “Public awareness and reporting are essential to early detection, which provides the opportunity to contain an infestation before it becomes a widespread problem.”
Spotted lanternfly causes direct damage by sucking sap from host plants while secreting large amounts of a sugar-rich, sticky liquid called honeydew. This honeydew and the resulting black sooty mold can kill plants and foul surfaces. The honeydew often attracts other pests like yellow jackets, flies and ants, affecting outdoor recreation and complicating crop harvests.
From late summer to the first hard frost, spotted lanternflies are in their adult stage and easiest to identify. Adults are roughly one inch long. Their folded wings are gray to brown with black spots. Open wings reveal a yellow and black abdomen and bright red hind wings with black spots transitioning to black and white bands at the edge.
Female spotted lanternfly lay egg masses in the fall, which resemble old chewing gum, with a gray, waxy, putty-like coating. Egg masses can survive winter temperatures to hatch in the spring. Hatched eggs appear as brownish, seed-like deposits. Spotted lanternfly juveniles are wingless and are black with white spots, developing red patches in their final juvenile stage.
If you find a spotted lanternfly egg mass, juvenile or adult, take one or more photos, make note of the date, time and location of the sighting, and report it to MDARD via email at MDA-Info@Michigan.gov or by calling 800-292-3939. If possible, collect a specimen in a container for verification.

Ever been to the Michigan town of Decatur? It’s one of our towns where another popular entertainer lived.
It’s a stretch to think today’s generation would know who Candice Bergen is…..aside from a good many movie roles, she’s most recognized as the star of the CBS television program “Murphy Brown” from 1988-1998.
Well, it’s not her I’m referring to.
It’s even a BIGGER stretch to fathom that anyone from today’s generation would know her father, Edgar Bergen, one of America’s most popular, and probably THE most popular ventriloquist of all time.
He began his career in vaudeville and some films in the early 1930s, but it was after a radio appearance on Rudy Vallee’s program in 1936 when his profession took a must-needed boost. Because of this successful appearance, Bergen and his dummies - Charlie McCarthy, Mortimer Snerd, and Effie Klinker - were instantly hired for another radio show, “The Chase & Sanborn Hour” which lasted from 1937 to 1956. During his gig on the show, Charlie McCarthy’s on-air feuds with comedian W.C. Fields made the show even more popular. After the show left the air, Bergen appeared as a guest on television shows and a few minor film roles until his death in 1978 at the age of 75.
Born in Chicago in 1903, the family moved to Decatur, Michigan (in Van Buren County) not long after his birth. Many bios state he was born in Decatur but that’s not the case. There is a restaurant in Decatur – the Hard Times Family Restaurant – that is decorated with numerous mementos of Bergen’s career. The walls are full of memorabilia and collectables – even Carbon-copy dummies of Charlie McCarthy and Mortimer Snerd. There’s even a menu item named after him – the Edgar Bergen Burger.
However, Bergen did not grow up in Decatur. His family moved again when he was only four years old. But that doesn’t stop Decatur from immortalizing him even further; one of the town streets is named Edgar Bergen Boulevard.
Even though he only spent his first four years in Decatur, Edgar had feelings for the town, as he paid it one last visit in 1976, two years before he passed away in 1978.
One last thing: Edgar Bergen was unfairly criticized for moving his lips when he made his dummies talk, and I'll tell you why it's unfair. In the early stages of his showbiz career, Bergen was an excellent ventriloquist and definitely made his dummies 'talk' without moving his lips.....however, once he appeared on radio, there was no need to keep his lips still. The audience couldn't see, right? So throughout his two-decade radio career he got used to moving his lips. During that time he appeared in films, and his lip movement had become noticeable. And it remained that way until he passed.
Take a look at the gallery below for some pics of Bergen and vintage shots of Decatur as it looked during Bergen's early life.
