There's a grain of truth in here, but not quite. One in every four or so (not quite, but we can roll with it regardless) identified species of animal is a beetle. Not one in every four animals, by population nor overall species.

The reasons for this is are many, but may include because beetles are big, easy to catch, agriculturally-significant, and are particularly easy to pin and study, dramatically boosting the count of beetle species we work with on an academic level (lending to higher identification rates). There are also just a shitload of beetle species, naturally.

Scientists estimate something closer to ~10 million species of animals, which would still make beetles a huge percentage of the species, but a far cry from 25%. If you looked at the total number (estimated) of individual animals, beetles are pretty insignificant.

I love how when new waves of people discover old technology, there are always these types of fundamental questions.

Firefox has been here for a long time. Plenty of people use it. Casuals don't care about what browser they have installed. That's the entire conversation!

The actual interesting part of these questions popping up is the staggering lack of awareness. We can click your profile, and, as I've linked above, see you try Firefox for the first time, ever. Then, you proceed to ask fundamental questions like the one in this thread without referencing that you're brand new to the software, or that you haven't bothered to look up previous discussions.

As for being the "reasonable conservative" in the room, well, I'll let that speak for itself.

Your entire argument applies to books as well.

It's a bad argument.

I'm gonna go hard for a second here and say that they most certainly do not look "really silly".

Your echoing of a term unique to a single author and acting unimpressed when someone hasn't heard of it is weird. If you were couth, you'd have linked to the work or defined the term after using it. As it stands, your use of the term "secular cycle" is nothing more than a smarmy debate-trap with absolutely no constructive merit.

This was a hard post to read.

You're not shadowbanned from YouTube. The creator you're commenting on has simply "hid" you from their channel. Which ironically is a shadowban, just on a creator level.

The level of panic and outrage you've displayed here despite not having a clue as to how the mechanic you're discussing works is remarkable.

[-] kep@lemmy.world 36 points 11 months ago

Most excellent.

Are we under any impression that this will have long-term support? Or just a novelty to enjoy while it's here?

Y'know, I read that entire thread, and it really doesn't come across as you're representing it.

The mods are spitting rage over there. They're outright insulting every aspect of reddit. I feel like focusing on the idea that because they made a post there they must still be active users is a stretch and unfair.

Of course, we know too many people still use the site. But it's hard for me to get on board with a blanket "fuck the mods" based on that thread alone.

They love milkweed. You can attract them to your yard if you plant some. I've personally raised large colonies of these for research, they're truly remarkable insects for a number of reasons, beauty of both the larvae and adults being chief among them.

One of the more common issues that plague the Monarch is Ophryocystis elektroscirrha, a parasite that can be identified by examining a body-dust sample through a microscope. OE is passed on via spores that are consumed, and if an animal is affected by OE and undergoes metamorphosis, it will emerge with a number of defects that often lead to reduced lifespan or imminent death.

Sadly, in research environments, the only way to deal with OE outbreaks (a sign of poor control) is to euthanize the animals to contain the spread of spores. This is typically done using a freezer, which ostensibly allows the animal a peaceful death by slowing down its metabolism and numbing its senses.

Nobody is talking about it, but does that advertising exec that Musk hired for CEO take a massive hit to her career for any of this?

It seems surreal to have a ghost CEO who isn't responsible for anything such a large company does. But that's exactly what's happening here.

I know the timing lends itself to dogpiling, but honestly? Good for them. Throughout the fog, reddit made a solid choice - awards and coins were absolutely fucking stupid. I had posted regularly on reddit since 2011 or so. The coin shit distracted from the original sorting system - upvotes/downvotes.

Of course, hindsight belies that even that algorithm was bullshit the entire time. Alas, fuck reddit. Good riddance.

Oh my God. This is awesome.

"We need to tighten the purse strings!!1" quickly became "open the coffers!" as soon as they hit a speed bump.

Seriously epic. With the amount of vote manipulation going on over there, this will be a complete and utter failure. I guarantee it will be pulled in a month or two.

Also, there's a typo in this community's sidebar (first sentence, "it's" -> "its"). I don't want to be pedantic, but let's clean up some of these forward-facing things as we welcome more folk into this arena.

Did two people with almost identical names make Lemmy? If not, can someone (who actually knows what they're doing) fix up the Wikipedia article? Someone shouldn't be referred to as a creator and a co-creator, and then obviously, the typo.

Tiger beetles are notable for one thing: their speed. They can move up to 9km per hour, which given their size, is spectacular (a 1:125 body length per second ratio).

Because they run so fast, they can be observed pausing after short bursts. Scientists suspect this brief respite is a way for the insect to get its bearings. But, like a lot of entomology, there are other ideas...

These aquatic insects are intimidating-looking, with large modified forelimbs. Although they live in the water, they're air-breathers, and like virtually all insects, can fly when necessary. The modified forelegs, referred to as "raptorial" (predatory) legs, have a similar function to that of mantises — they grab and secure prey to be consumed. Preferred prey is soft-bodied, but Giant water bugs don't need to discriminate, given how powerful they are for their size.

However, unlike a praying mantis that chews its prey with a traditional insect-mouth plan made of many mandibles, since Giant water bugs are Hemiptera, they have a straw instead of "teeth." This means that they, like some assassin bugs and spiders, rely on injecting digestive juices into their immobilized prey, then sucking up the now-digested innards.

In my personal experience, these things are scarier than they look, but they're absolutely capable of pinching or piercing you with their forelimbs, and they move fast in the water. I personally stay away from them.

Share pictures, ask questions, and solicit identification. Higher-quality pictures are easier to identify. Do not guess the species of an insect, use a dichotomous key to be sure.

Please understand that handling wild animals, bugs or otherwise, can be dangerous. Seek immediate medical attention if you’ve been bitten or stung by something.

They're huge. But they only experience this form for a very short period of time! Most of their life is spent underwater in their larval stage, where they hunt other animals and cling to objects to manage currents.

In their mature form, shown, they aren't even really interested or capable of sustaining themselves. Indeed, they just wither away and die. It's sad, but for insects, the dramatic life cycles are part of what makes them so special.

These are photos of slides and sticky traps featuring various Chalcids, mostly Fairyflies, from a research project many years back.

The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcidoid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1,400 species. Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from 0.5 to 1.0 mm long.
