PIC: You never know what creatures you'll find in the sludge

O the wonderful world under the microscope.

Our Biologist Carrie Millward sent us this image of a non-biting midge larvae she found in a sample of solid material (sludge) in our treatment process. They look scary, but they're common in wastewater. As they grow up, they become a good indicator of water quality.

We'll need to add this one to our list of scariest-looking microscopic creepy-crawlies for sure. Thanks, Carrie!

PIC: Just your normal everyday swarm of bugs so thick you can see it on radar

This is not a thunderstorm warning. It's not a weather alert or special report.

It's just bugs. Lots and lots...and lots...of (harmless, but yes annoying) bugs over Lake Erie near Toledo.

BLOG: Midges vs. mayflies: Let's clear the air and the confusion

Midges, mayflies, muckelheads, this can all be very confusing. And all of them can be very annoying. We'd like to help clarify a bit of the current bug conundrum.

Let's start here: There are midges (also known as muckleheads), and there are mayflies. They are different, but they're both related to the quality of our Great Lake.

Midges and muckleheads


The shores of Lake Erie have been teeming with these little guys lately—muckleheads. Fox 8 meteorologist Scott Sabol has shared a few updates over the last week.

We verified his total. He was off by three.

But what are these pesky buggers? These are known as muckleheads or midges. Or if you want to impress friends, call them Chironomidae.

They hatch over Lake Erie in the spring and fall and make their way inland. They don't bite and they're not harmful, but they can still be a nuisance during a beach barbeque. According to our Senior Investigator Ron Maichle, they are organisms of interest because they have varying tolerance of pollution. The Sewer District does collect macroinvertebrates to study water quality, but we do not study the adult midge population.
