I received an email this morning from a friend up the street who had found this insect near North Bay, Ontario, and was unsure as to what it was. I love identifying insects for friends and family! As luck would have it, I knew right away what this fascinating creature was. A Giant Water Bug! This insect falls into the true bug category. So what is a true bug? Without getting too technical, a true bug is from the Hemiptera order of insects. True bugs have a specific wing structure which puts them into this classification of insect. The term Hemiptera actually means "half wing"". In this case, half of their front wings are thick and leathery, while the other half are membranous. Another important criteria for the true bug designation, is the presence of piercing, sucking mouthparts. These critters cannot chew! Instead, true bugs pierce their food with their beak-like mouths, pumps saliva into the food source to partly digest it, and then sucks it up like a straw. The piercing mouthpart of this particular insect cannot be seen in the photos above, as it is tucked underneath its "nose", if you will.
So, the giant water bug has a few other names that it is known by. One is the toe-biter, and the other is the electric light bug. The toe-biter name came about as it is often stepped on by unsuspecting victims and the electic light bug name comes from its attraction to electic lights at night. Oh, by the way, these things can fly. Kind of makes June bugs a little less freaky, huh?!
This insect, which is the largest of the true bugs, can be found in shallow freshwater lakes, streams, ponds and pools. I found one doing laps in my pool last summer while I was vacuuming it out. I didn't stick around to play with it, as these critters can have a powerful bite! Just so you know, I am scared of PLENTY of bugs! I just find that the more I learn about them, the less there is to fear.
Juicy Tidbits
- These common brown insects range in size from 1 to 2 3/8 inch
- They have flattened hind legs that are used for swimming.
- Their strong forelegs are used for grasping prey while the insect thrusts its piercing beak into it.
- There are two tail-like breathing tubes at the rear end of the toe-biter that help it to breath while underwater. When it needs air, it will raise its abdomen to the surface of the water and extend the breathing tubes.
- Eats other insects, tadpoles, small fishes, salamanders and careless people's toes. (kidding about the last food item!)
- These critters will feign death if picked up, but can suddenly stab with their beaks! This is not an insect that I would recommend handling at all!!!
I have found some excellent websites if you would like to know more about the giant water bug
I also used my trusty National Audubon Society Field Guide to North American Insects & Spiders, page 463 - 464 for information.
Special thanks to Marc, Meaghan, Keith and Dean for finding this insect and sending it my way!!
I found one in my yard in St. Catharines, Ontario. Everyone tried to tell me it was a cicada but I knew differently. Glad you posted this photo. I did handle the bug with gloves on. It was very strong. I let it go but found it later in the street. He had been stomped on, but we did save it in a jar for the kids to admire. It is quite a bug I must say.
ReplyDeleteHi Leeanne!
ReplyDeleteThey are quite the fascinating (and rather creepy) bug, that's for sure! Thanks so much for checking out my blog. : )
Thanks for this information. My Dad told my 7 year-old son about how when he was 7 or 8 he snuck up on a little frog down at the pond and was just about to grab it when he noticed it was collapsing, like a balloon with a slow leak. He watched it for a long time until he saw a huge waterbug swim away from underneath it. We had to research it. Dad said it was as long as his finger and seeing that one, it sure looks like it could be the length of a child's finger. Pretty cool as long as it isn't snacking on your toe.
ReplyDeleteThat would make for a cool time-lapse video.... watching a toe-biter drain its prey.
ReplyDeleteThanks for visiting my blog and leaving a comment!
Take Care
This is great! Me and my wife just found one of these on our front deck up in Wawa, Ontario and had no idea what it was! kinda glad I didn't pick it up with my hand...LOL.
ReplyDeletejay and polly
I'm glad you didn't pick it up too! Thanks for dropping by and reading my blog. If you ever find a bug and don't know what it is, take a picture of it and email it to me for an i.d.
ReplyDeleteTake Care,
Yvonne
we found one in our pool (oshawa ont) have never seen one before and was wondering what it was and where do they come from? Thanks for the info.
ReplyDeleteThey fly in looking for a deep enough body of water to spend the winter in. Your pool might be just the place...I've got two hanging around my skimmer basket the last couple of days. They don't seem to mind the shock-level chlorination...
ReplyDeleteWe had one in on our deck last summer. No pool or streams, but one neighbour has a pool so maybe that was the attraction. They fly and bite-ugh! Smack first, as questions later!
ReplyDeleteBTW-In Ottawa Ontario.
