Who knew that by being lazy with yard work, I was doing the right thing all along. I do see fireflies out back during the summer. I thought it was just that we live fairly close to the edge of town.

Nature is best cared for by leaving it the fuck alone.

[-] Timecircleline@sh.itjust.works 18 points 4 months ago

Other than the forest fire prevention that native Americans used to perform, I would agree.

[-] Bazoogle@lemmy.world 12 points 4 months ago* (last edited 4 months ago)

Even this can have negative impacts. More frequent, smaller forest fires allows for the "fuel" to be burned off in small quantities. If you go too long without the fuel being used, it builds up, until you get a very large forest fire. Which happened a few weeks ago (sparked by the other right conditions, of course)

[-] Timecircleline@sh.itjust.works 10 points 4 months ago

You just described the cultural burning practices that were in place for thousands of years though.

[-] Bazoogle@lemmy.world 2 points 4 months ago

Right, which I would say is not forest fire prevention, since they are starting forest fires. It's more so forest fire mitigation. Perhaps that's getting into semantics, but I thought it was a necessary clarification.

[-] Timecircleline@sh.itjust.works 2 points 4 months ago

Thank you, no that makes total sense

[-] MonkderVierte@lemmy.ml 9 points 4 months ago* (last edited 4 months ago)

Yes, occasional small forest fires are actually good for nature. Young trees csn grow, more resistant than the old wood against storms and pests. A lot in nature even relies on those cycles, pioneer weeds as an example. We really only made things more convenient for us short term with managed woods, without understanding half of it.

[-] BigBananaDealer@lemm.ee 3 points 4 months ago

i thought there was a group that actually made small fires in forests for this reason. im pulling from a severe backlog in my mind so im just going to comment this and someone can tell me if im wrong or right 😂

[-] pelespirit@sh.itjust.works 79 points 4 months ago

Okay scientists, is this for real? Would leaving leaves out help with the fireflies, because they really are rare.

[-] Jackinopolis@sh.itjust.works 147 points 4 months ago

Yeah, leaving leaf coverage is great for all kinds of larvae. Leaving them alone also slows weeds from growing and as the leaves break down they fertilize the soil.

The modern problem is that there are not enough critters roaming around to naturally step on foliage to break them down.

Send the kids to play outside, easy

[-] Tikiporch@lemmy.world 10 points 4 months ago

So some sort of cylinder with animal feet attached, I drag it over the yard a couple times through the fall and winter?

[-] Worx@lemmynsfw.com 6 points 4 months ago

Please do not kill a bunch of animals and attach their feet to a cylinder 😭

[-] prex@aussie.zone 2 points 4 months ago

You win the gruesome mental image for this afternoon - nice.

I think it depends on the species. Also, most species have non-flying females.

[-] Itdidnttrickledown@lemmy.world 67 points 4 months ago

Around here they made a comeback in 2020 and 2021 during the pandemic. The reason why was they stopped spraying the forests for pine beetles. It was noticeable and now its back to nearly nothing. Its poisen. Nothing more, nothing less. The fireflies die so some undeserving investor gets more money.

[-] Moobythegoldensock@lemm.ee 49 points 4 months ago

The sprays really kill them. The fireflies will not cross into my neighbors’ lawns, where they treat their grass.

[-] Speiser0@feddit.org 3 points 4 months ago

Your neighbor does what with their grass?

[-] Moobythegoldensock@lemm.ee 4 points 4 months ago

Spray shit on it to kill the dandelions.

[-] Speiser0@feddit.org 1 points 4 months ago

When you say shit, do you mean actual shit or herbicides? One of those would be absolutely disgusting, and the other doesn't kill dandelions, I think.

[-] Moobythegoldensock@lemm.ee 2 points 4 months ago

You know, I haven’t actually asked them what it is they spray. All I know is almost everyone in my neighborhood does it, then waters their lawn constantly and mows short twice per week. And like 1/3 of them burn their leaves every fall and triggers the hell out of my asthma and allergies.

Which is silly because I live in the Midwest: grass doesn’t need any help to grow here. I mow a little longer every week or two in the spring and every 2-3 weeks in the summer and my lawn looks lush with 1/3 of the effort and not pouring a bunch of crap on it. And my trimmings decay just fine without sending a plume of smoke to my neighbors.

[-] Arghblarg@lemmy.ca 49 points 4 months ago

Same for ladybird beetles (ladybugs)! They love undisturbed autumn leaves and are natural pest control, so you should give them any opportunity possible to over-winter their eggs in your yard :)

[-] NABDad@lemmy.world 48 points 4 months ago

I'm doing my part. Haven't raked leaves in at least 20 years.

[-] MonkeMischief@lemmy.today 9 points 4 months ago

Me neither!

... Although I live in a desert and haven't seen fireflies anywhere else in ages... Lol

[-] JohnnyCanuck@lemmy.ca 17 points 4 months ago

Now let's talk about the Kentucky bluegrass lawns the leaves fall on...

[-] uid0gid0@lemmy.world 16 points 4 months ago

Grub killers like Grub-x kill firefly larva as collateral damage. The thing is firefly grubs eat other grubs so if you made your area nicer to fireflies you wouldn't need the grub killer.

[-] finitebanjo@lemmy.world 13 points 4 months ago* (last edited 4 months ago)

I thought only the males lit up? Not judging, but egg laying might pose a problem.

[-] Saurok@lemm.ee 9 points 4 months ago

It's both. It's a beautiful little call and response like system they have evolved to do. Typically the males will light up while they are flying and the females light up on the ground. There are some species that are predatory though and will mimic and use the lights to hunt the others.
