We are getting reports that the mayflies have subsided in the Port Clinton, Ohio area. This doesn't mean they're gone, just not near as heavy as they were.

"We just moved to Lake Wisconsin near Poynette, WI and today are experiencing our first exposure to mayflies! Thanks for your website and info about these insects. We had no idea and thru my googling, found out what the heck these were. So, mayflies are alive (for a short while) and well at Lake Wisconsin." Thanks Celeste. Nice to know Lake Erie isn't the only place mayflies are thriving.

"Mayflies came into Avon Lake (Ohio) over the June 19/20 weekend. More than I have seen in years. They are as far north as the Avon/Avon Lake border. Last year, they came in on June 18th but stayed much closer to the Lake." Thanks for the report, Jerry!!

Here's one that made us chuckle. Tycho wants to know "Do you have any Mayfly recipes?" I've never heard of anyone eating mayflies - but hey, kangaroos are a nuisance and Australians are eating THEM now!!

Paris says... "They invaded Vermilion last night. I have motion lights outside as well as a neighbor that has a security light that shines on the side of my house and the front of my garage (which are white). Needless to say, my house is covered. They've sneeked in when the door has been opened and I've been finding them all over the inside of the house." Yes, Paris, they will sneak in. We suggest sitting one on your shoulder and start whistling that song... My, my, my, what a wonderful day. There's a mayfly on my shoulder.... :<)

Suzy from Lorain.... "They are here in Lorain Ohio, Hatched last night and now covering every surface of every building. These little buggers are gross!"

Cheryl writes from Detroit Beach, MI which is just north of Monroe... "This year seems to be extremely bad. We live at Detroit Beach on the lake and our house and yard are covered. Anything to spray to reduce these? We keep most lights off but everything is covered. Any help?" No spray will help, Cheryl. My only advise is to try and keep the lights off... Oh, and don't wash them off your house with the garden hose!! You will create one soupy, stinky mess!!

Ruby from Harborcreek Twp, PA emailed - "Last night, about 8 PM, we had a huge swarm of mayflies above our house. It sounded like an air leak, a loud hissing noise! We live 1/2 block from Lake Erie. We never experienced that before!" I know what you're talking about, Ruby, because I have heard that sound myself. Pretty amazing!!

A message from Mark - he says "They're back at Catawba!"

Mayflies are arriving in Port Clinton, Ohio this evening!!
|
|
|
With mayfly season only 2 months away, we hear from Terry... "We like to go to Port Clinton to fish 2 - 3 times a year. A couple of times we arrived when mayflies were at their heaviest. It wasn't a fun time fishing. To make 2010 a better experience, can you tell me when you think the flies will be at their heaviest? I don't want to come then." Terry, just like Mother Nature, there really no predicting when the mayflies will be heavy. And it could vary from night to night. Just remember they're harmless and a good sign that Lake Erie is getting healthier!

We have added a link on the More info and links page to a great article on mayflies and how they're affecting Lake Erie. It's published online by the Great Lakes Echo.

It appears that mayfly season is about over, but if you looked real hard in Lakeside Ohio, you could still find a few hanging out on the pavilion by the water. It's always nice to find a few around.

Annette says "These little soldiers were all over the Venture Resort building on the side facing Lake Erie." This was on Kelley's Island. You can see Annette's photo on our 'Weekly Photos page.' Email your pics to photo@mayflynews.net

We were still hoping to see more pics from fans, or those that are not fans, of Mayflies!! The funny or goofier, the better. Email your pics to photo@mayflynews.net

For all those challenged by telling the difference between a mayfly and a mufflehead (no, not you, it's those other idiots), We have added info on identifying muffleheads on our 'Mayfly Facts' page. It's down towards the bottom of the page. Thanks to Gwen from Columbus for the great visual aids.

The mayflies have slacked off in the Port Clinton area. I'm sure we'll still see a few here and there for the next month or so.
We could also get a burst of them some night with a hefty north wind.

Jerry says "Mayflies have invaded Avon Lake! They are everywhere along Lake Rd, Electric Rd. etc. Must have come in last night." Thanks for the update, Jerry!!

We are receiving reports that in the last few days walleye fishing has taken a nosedive due to all the mayflies surfacing. Many mayflies become a yummy fish snack instead of coming onshore to annoy you!! Also, Denise Kumar says no screaming when riding the coasters at Cedar Point or you may end up with a mouthful of mayflies!! Yum, Yum!!

It's Official!!!! Mayflies have invaded Port Clinton in a BIG WAY! The onslaught has begun. We're looking forward to seeing those photos, folks.

They're HERE!!!! Mayflies started appearing overnight in the Port Clinton, Ohio area. Not a strong showing yet - just a few. Kind-of-a teaser of what we know is probably coming.
Meanwhile, Tim and Debbie from Conneaut, Ohio (that's waaay up there in the northeast corner of Ohio in wonderful Ashtabula County) moved to within one quarter mile of Lake Erie and are finding out what a full bore onslaught of mayflies is like. They commented that it's much worse than being 3/4 miles away where they used to live.

Pam says "This is the best site! Does anyone know approximately when these pests will hit Port Clinton this year? Since they're already in Euclid, maybe we could judge better if the timing on their movement along the coast has been tracked. "
Hi Pam, it is a bit baffling that the Eastern part of Lake Erie is seeing mayflies before us. One would assume since we are at the shallower end of the lake, the water would warm up quicker here and we would see them first. This will be an interesting thing to track.

Jennifer, who owns a vacation condo on the Lake in Ashtabula says "The mayflies are here in full force. My Mom was here on Sunday, May 31 and said they were here then too. My question is how long do these mayflies typically stick around?"
Well, Jennifer, looking back on past information, they typically hang around at least into August and sometimes into September! Of course they do thin out as the summer progresses, so you have that to look forward to.

Mike from Euclid, Ohio emailed to say that "Over the past 2-4 days we've gotten bombarded." Thanks for the update, Mike. We still have yet to see one in Pt. Clinton.
Mike was looking for ways to keep mayflies from covering his house - especially the front door. All I can tell you, Mike, is keep those lights off. And remember, as tempting as it is to take the garden hose and wash them off, DON'T DO IT!! You will have the biggest stinkiest mess you ever saw!! Got a neighbor you don't like? Suggest it to him. :-)

Andrea writes... "I love this website. Have the mayflies arrived? We are coming to Port Clinton for the Memorial Day weekend and just want to prep the family beforehand."
Not as yet, Andrea, but that doesn't mean we won't see them before this weekend!! Thanks for emailing.

We are receiving reports that mayflies are already showing up in towns located along the Portage and Sandusky Rivers in Ohio. River waters warm up sooner than the bottom of the lake so this probably brings out the mayflies sooner.
|
|
|
After a long & cold Winter, we are experiencing a cool wet Spring. But warmer weather is coming and we should be experiencing mayflies within the next 30 days. Stay tuned!
|
|
Mayflies are regularly spotted 30+ miles from the Lake Erie shore. Now, they may not see more than four or five of them in an entire season, but they are around. They've even seen a few in late September!!
|
|
I spotted a small mayfly in Bowling Green, Ohio - actually he landed on me!! Bowling Green is a good hour drive from Lake Erie. Yes, I would say mayflies are in the rivers.
|
|
A strong northern wind off the lake and warmer temperatures combined to finally bring in huge amounts of mayflies on Friday evening. On Saturday morning, it was difficult walking in and out of the house without several catching a ride on your shirt. All the houses in the area are covered with our winged wonders! After a slow start with just a few showing up every night, they made a full showing on Friday evening.

Whoops...
On about June 1st, 2003, Port Clinton, Ohio was inundated with large swarms of bugs. The local daily newspaper jumped right on the story and had it front page - the mayflies have returned but are smaller this year. After all the locals quit laughing, they informed the paper that the bugs were indeed muffleheads and not the famed mayflies. Muffleheads are harmless bugs that are similar to mosquitos and just slightly larger - but they don't bite. |

The National Geographic Magazine did an article on the mayflies of Hungary's Tisza River. See the May 2003 issue. The article has some superb photos. Their mayflies are somewhat different from ours having large bug eyes and blue wings.
Thanks goes to Suzanne Fickes at Ohio State University for sending me a copy of the magazine.

1999 saw these guys make headway inland as far as 40+ miles from Lake Erie. They were either blown in or are also living in the river. In the case of Pemberville, OH, I find it very hard to believe that june bugs flew that far inland. They are apparently thriving in rivers. Pemberville has the Portage River running through the heart of it - and Pemberville has Street Lights!

Minature May Flies!
On a 1999 excursion to South Bass Island and Put-In-Bay, Ohio, I discovered a tiny version of our friendly flyer on a gentleman's back ahead of us in line. This entire bug measured no more than three-quarters of an inch long - head, tail, and all! What a time to be without my camera! Hopefully, I will come across one again... this time with camera in hand.
