Hello bugman,
I found this insect in my lawn after it was cut. We don’t know what it is! Do you?
We live in Ringwood East, Victoria.
Thank you for your help!

Backswimmer

Dear Oscar,
Do you have a pond or swimming pool in your yard or nearby?  This is an aquatic True Bug known as a Backswimmer in the family Notonectidae.  Though they are aquatic, adult Backswimmers can fly from one body of water to another.  They are predators that feed on other small water insects and invertebrates, even feeding on small fish and tadpoles.  LIke other True Bugs, they have mouths designed to pierce and suck, and they can deliver a painful bite, causing them to be called Water Wasps in North America.  See the Australian Museum for more information, including:  “Backswimmers get their name because they are great at backstroke. Using their legs they swim upside down at the surface of the water.”

Can you help identify what this is please ?
I found it swimming in our pool after a few days of heavy rains.

Backswimmers

Backswimmers

Dear Matthew,
These aquatic true bugs are Backswimmers in the family Notonectidae.  According to BugGuide they are:  “Aquatic bugs that often swim upside-down. When resting at the surface, body is typically tilted with the head downward”
and they “Prey on other aquatic insects and sometimes on small vertebrates.”  Backswimmers can fly, which enables them to seek a new home if their pond dries out.  We don’t know what would have caused them to relocate to your pool after the rains.

Daniel,
Thank you very much for your reply.
Fantastic info. My son has taken matters into his own hands and relocated them to another improvised pool. They’re doing well.
Can they fly far ? Perhaps the winds carried them a little further than normal.
Also, my pool is a salt based pool rather than chlorine, would that allow them to survive better than in the latter ?

Dear Matthew,
Since Backswimmers are predators, they will not remain in a body of water that does not provide a food supply.  Insects will not live in a chlorinated pool, but many insects will fall into the water.  Backswimmers are air breathers, and if the chlorine is not strong, we imagine they can survive in a chlorinated pool.  We also believe there are some species that can inhabit brackish water, which is a blend of fresh and salt water.  They can fly considerable distances.

Hi!
I was out hunting in the woods today and accidentally stepped on this huge bug (God bless)! I’m very curious as to what it was. The current temperature is around 10 degrees Celsius as we’re right into the fall season.

Dear Logan,
This impressive creature is a Giant Water Bug or Toe-Biter.  Toe-Biters are aquatic predators that can also fly, so they can move from pond to pond or seek a new watery habitat if their home dries out.

Can you ID this bug which was found in our garage. Runs fast. Possibly soldier bug ?
Thank you,

True Bug, but which one???

Distorted image of Toe-Biter

Dear Veronica,
We wish your image had more detail.  We are relatively confident that this is a True Bug in the suborder Heteroptera, but at this time, we cannot provide any additional information.  It most closely resembles the Narrow Stink Bugs in the genus Mecidea that are pictured on BugGuide, but we do not believe that is a correct identification, especially as there are no sightings in the northeast.  Can you please tell us how large this insect was and also send additional images if you have any.  Meanwhile, we are going to seek a second opinion from Eric Eaton.

Eric Eaton provides an obvious ID
Daniel:
Kinda funny that it *ran* fast considering this is actually an aquatic insect that *swims* fast.  LOL!  This is a giant water bug in the genus Belostoma, family Belostomatidae.  They fly well and are sometimes attracted to lights at night.  Well, you know that already, and know they are also called “toe-biters.”
Eric

Interesting Eric.  We are no strangers to Toe-Biter identifications, and at first we thought this might be a Water Scorpion.  The image appears to be distorted, and that threw us off, combined with the “runs fast” comment.

Comment
This reminds me quite a bit of a Belostomatid, but it looks like a somewhat stretched picture. If you vertically compress the picture a little bit, it’s easier to see. Then again, it could be something completely different! I look forward to hearing what Mr Eaton says. The true bugs are my favorite group to work with, there’s always surprises.
sccabrian

Dear sccabrian,
You are correct.  See Eric’s response and our reply.

Hemipteran Corrected Perspective

Hemipteran Corrected Perspective

Ed. Note:  We feel really stupid because our first thought was aquatic bug, but it just did not look right.  We never suspected altered perspective.  Of the Toe-Biters in the genus Belostoma, BugGuide states much of fascination, including “overwinters as an adult; mating and egg laying occurs in late spring or early summer” and “Females cement their eggs to the backs of males, who swim with the eggs attached, providing aeration and protection until the eggs hatch.”  This is one of the few examples in the Insect Class where the presence of the male improves the chances of survival of the young, AKA paternal behavior.  We believe the male Sexton Beetles contribute to the care of the larvae.

Thank you Daniel. Unfortunately we have no other images. We think he is about an inch long +/- a bit. I know we are horrid

Hey Sir, I am a Marine stationed out here in Africa and saw the weirdest looking beetle outside my house. I have never seen anything like it on discovery channel. The things was huge and aggressive. Not only did it have huge claws to grab stuff with but it fly’s also! It wasn’t even scared of me it actually tried to attack me. I didn’t squish the monster he took off and caught a moth in flight. Hopefully you can help me identify this guy.

Hi Zachary,
It is easy to mistake this Giant Water Bug in the family Belostomatidae for a beetle, but closer inspection will reveal that instead of mandibles adapted to chewing like the beetles, the Giant Water Bug has a mouth designed to pierce and suck fluids from its prey, consistent with the mouths of Heteropterans, the True Bugs.  Giant Water Bugs from North America are often called Toe-Biters because unwary waders have frequently received a painful bite if they step on one of these aquatic predators, or otherwise carelessly handle them.
