Hello!

Thanks SO much for uploading an observation to Vital Signs! You're helping so many scientists better understand streams and aquatic ecosystems around the state of Maine.

I do, though, would love to learn a bit more about why you think this BMI is a giant water bug. A key characteristic of the giant water is the large pinching structure (they look kind of scary!) on the front of the body [for example: https://www.insectidentification.org/insect-description.asp?identificati... ]. From your photos, I cannot see this feature. Did you see these funny-looking front structures on the BMI you found? Or, if not, what led you to believe it was a giant water bug? A bit more info would help me confirm this review! :-)

Thanks so much for contributing to VS! Great work, great observation! Keep it up, and I'm SUPER EXCITED to see what you observe next... and also learn more about this cool find!

Best,
Kansas
