Mayfly

Dear Gerold,
Your image is beautiful.  This is NOT a Damselfly.  It is a Mayfly in the order Ephemeroptera.  We found a perfect match to your individual on Wildlife Trust, but alas, it is not identified to the species level, though the site does state:  “There are 51 species of mayfly in Britain. They are common around freshwater wetlands, from fast-flowing rivers to still lakes, where the larvae spend their lives underwater feeding on algae and plants. The adults hatch out, usually in the summer, and have very short lives (just hours in some cases) during which they display and breed; hatchings of hundreds of adult mayflies in the same spot at the same time often occur. Many species do not feed as adults as their sole purpose is to reproduce and once they have mated, they die. The common name is misleading as many mayflies can be seen all year-round, although one species does emerge in synchrony with the blooming of Hawthorn (or ‘Mayflower’).”  We believe we have identified your species as
Ephemera vulgata thanks to BugLife which states:  “Mayflies are unique as insects in having two winged adult stages. After emerging from the water they fly to the bank where they shelter on the underside of leaves or in the grass. They then moult again, leaving behind their drab ‘dun’ skin to reveal their shiny ‘spinner’ skin. Following this moult they fly back to the water and form mating swarms dancing above the surface.”  We are post-dating your submission to go live to our site later in the month while our editorial staff is away on holiday.

Fascinating! Thank you for the reply
I need to correct the data on the photograph: it was taken on 2nd June 2017 on the banks of the Derwent River in Rowsley, Derbyshire, UK
postcode DE4 2EB.
The mayfly is sitting on a red car. I attach another image where the reflection is nice.

Hi,
Since a week, my house wall outside is filled with 100-200 tiny larvae.
I live in Los Angeles. I would say they are 4-5mm long maybe.
Thanks!

Mayfly Exuvia, we believe

Mayfly Exuvia, we believe

Hi Rafael,
Do you live near the LA River or some other body of water?  Or, do you have a pond in your yard?  This looks like the aquatic larva of a Mayfly, or more accurately, the exuvia of a Mayfly.  When they near maturity, the aquatic naiads climb out of the water and molt, flying off as a subadult.  The subadult of a Mayfly is one of the only insects that molts a second time once it is winged, eventually emerging as a mature adult Mayfly.  Since the larvae are aquatic, they need a body of water in which to develop.  Do the larvae move?  If not, then they are simply the exuviae, or cast-off exoskeletons.

Thanks for your answer.
We live about 2 blocks ~8 minutes walk from the LA river which is really the suburban area…all concrete.
There are 2 swimming pools nearby neighbors, but they are usually taking care if them. Otherwise no other water besides sprinklers.
Thanks
Rafael

Hi there,, saw this little creature tonight. I’ve lived in this area all my life and I don’t recall ever seeing one before. Any idea what this little (about 1.5 inches) guy might be? And is that a stinger on his back end? Thank you!

Thank you for submitting your identification request.
Please understand that we have a very small staff that does this as a labor of love. We cannot answer all submissions (not by a long shot). But we’ll do the best we can!

Thank you for your quick response!  I’ve done a little research and it looks like my friend is a Mayfly!

We know you already identified your Mayfly, but it is such a nice image that we want to post it so our readers will learn to recognize Mayflies.  We believe your individual is a Giant Mayfly in the genus Hexagenia which we researched on BugGuide.  We also want to address your stinger question.  According to BugGuide, Mayflies have:  “usually three long thin tail projections (cerci); some species have only two cerci” but there is no further explanation.  The features of Mayflies are described on Mayfly.org including “It also features three long cerci or tails at the end if the body.”  Once again, the purpose or function of the cerci are not explained.  We will continue to research this matter.

Dear Bugman,
Yesterday, June 26th, as I drove to the edge of the Ohio River, in Louisville, Kentucky, a small swarm of these dragonfly like insects landed all over my car. I actually had one that took a ride to the grocery store with me, afterward! I suspect that they were juvenile dragonflies. Can you confirm?

Dear NB,
This is the shed exoskeleton or exuvia of a Mayfly.  You must live near a body of water.
