where I live, there is enough insects that even LEDs get swarmmed, sure way less than other light types, but with enough insects in the area it will still attract enough to be labeled as a swarm

there is a specific insect, native to where I live, that seasonally appears in the hundreds during their mating season and swarm literally every outdoor light possible

    sounds like the cicadas.

    we also those here but the ones I am talking about arent them, but we also seem to have cicadas like every year, some years there way more, and it is not like the other years are just erractic one offs, there are still plenty those, just not littering the entire hike trail path level

    click on article

    cover photo by cgp grey

    first heading of the article says that it's wrong and that I shouldn't read it

    I wonder when the next cgp grey video will come out. It's been a long while.

    That's not my experience. I have a nifty one AAA battery LED light, and when it's dark and warm out, and I turn it on, immediately mosquitos come to me. It's so irritating, sometimes I just don't turn it on, and I keep it off when entering my house, to avoid dragging the insects with me inside the house.

    The linked article is being changed as I type this. So it might come to a different conclusion.

    But to your point: maybe mosquitos come out more when it's dark generally, which correlates with you turning on the light. But the mosquitos are attracted to the CO2 in your breath (which they are) and not the light.

    But my experience is that I have less bugs (maybe mosquitos) when I use the red light on my headlamp instead of white.

    What you say sounds reasonable. It would take a year to determine the actual correlations up to a scientific standard, using proper experiments with controls, etc.

    But I still feel the LED light I have helps them at night, even if they could get a bead on me without it too.

    There could be all sorts of variables: which species of mosquito? Which LED lights? Which weather? Maybe some LEDs are invisible to some mosquitos, and some increase my visibility by 5%. Then, if the weather makes the rosquitos lethargic, 5% is not able to clear a threshold of increased swarming action, but when they are hungry and warmed up, 5% difference in their sense impressions is enough to make the mosquitos go bonkers. The possibility space is too large, which is why I am not a scientist. I don't have the stamina to do 100's of experiments to sort this out to a high standard.

    Cool, for the curious,

    Flying insects use moonlight to navigate. Since the moon is always above them, they orient themselves so that the light shines on their backs. That’s how they stay upright in flight.

    Moonlight contains ultraviolet (UV) and infrared wavelengths because it is merely reflected sunlight. Insects cue on UV, believing it to be the moon. When artificial lights transmit UV they look like moonlight so insects orient their backs to it. Consequently they circle the light and even flip upside down when the artificial light is pointing up to the sky!

    Incandescent lights transmit UV but LEDs do not. Insects are far less attracted to LED.
