Reply to Eli5: What causes leaves to fall off trees? by ShookeSpear

u/ShookeSpear

Thank you for saying that, really, I'm a little autistic (diagnosed) and was a little upset/frustrated. To me I gave the answer my niece would easily grasp (please see no offense). I'm really trying to help people in every way because this is one of the few things that brings me true joy. And I'm at war right now. I need some joy.

Again, positive vibes only in the message I'm trying to convey.

I'm happy I helped you out and gave a prebuilt answer for you to use with kids :)

For some reason I can't reply to your comment

The mechanism is called abscission - a layer of cells in the stalk of the leaf swell up and die, weakening the stalk so that the wind will dislodge the leaf. Before this happens, the tree draws resources out of the leaf (senescence), which causes the change in colour from green to browns and reds.

Reply to comment by travelinmatt76 in ELI5: how does blue lights attract insects and yellow lights acts like a deterrent? by Anubis2059

Hey! Sorry it took a while, fuck the war. We don't have electricity for the most part of the day.

Well in general I was correct assuming that's not how bugs work. But there is such a thing as light color preference. I've studied Lepidoptera (butterflies and moths), Coleoptera (beetles), and Hemiptera (true bugs). Each has a slight preference in wavelength (color). However, it's not like any moth won't fly to blue light or any beetle towards orange. There is a clear pattern, but that's not a rule.

However, since that's ELI5:

  • Moths and butterflies like more orange-> red-> infrared colors.
  • True bugs are more into blue-> cyan-> green-> yellow
  • Beetles seems to prefer ultraviolet -> blue-> cyan.

Some nice studies on the topic:
One, Two, Three

Have a wonderful day, take care and keep your mind curious!
Oh and fuck putin.
