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.
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.
