Loss of biodiversity (i.e. individual species dying out) makes the entire system less stable, since remaining species are less adapted to the environment. In the extreme, even if the individuals of a species, e.g. a particular breed of ant are displaced by another species, the system moves closer to a monoculture, which is prone to population shocks and other chaotic behavior.
Ultimately, all of Earth's ecosystems are connected through a vastly complicated food web. Even us. We've been blowing holes in that food web, roasting it, setting it fire, chopping off limbs, eradicating the places where it grows, etc.
This is actually very, very bad.
Asking questions is fine! It's great. It's how we learn. But cavalier comments like the OP are downvoted not because they are asking serious questions, but for stinking of militant ignorance.
Still, I find no harm in asking "what is it about this species that makes them stand out?" I was expecting to get factual answers along the lines of "these butterflies are tied to this specific other species and we know that this could snowball into X, Y, Z". I would've liked to hear something like this instead of the other patronizing answers and the accusative tone.

I'm getting downvoted just like OP. Am I being cavalier too?
I'm more concerned about our inability to have a discussion without assigning nefarious implicit meaning to questions. I realize that denying human impact on the environment is a reality in US politics. I'm not from the US. I don't understand much of these things.
If you don't mind me asking, what exactly in OP's question made it stink of militant ignorance? Am I displaying the same ignorance as well? Or am I only expected to perpetuate the outrage and never question anything.
For instance can I ask where this comes from "The extinction rate today is 100 to 1000 times higher than geological norms." or will it sound like I'm denying all human impact on the planet?
Because it's a symptom of a much larger problem. Namely, collapse of insects in general: https://www.theguardian.com/environment/2019/jan/15/insect-c...
Unless you've been living under a rock for the past few years, there've been multiple reported rapid declines across multiple species, not just "this species that for some reason stands out". Some species are naturally more studied than others (because of availability, accessibility, observability etc.), and when they collapse, it's can be immediately observed.
Robert Paine developed the theory when he went to a bunch of tide pools and picked out some of their starfish. What he found was that the ecosystems (isolated tide pools) where he removed all of the starfish rapidly collapsed. It turns out that the starfish were critical to controlling the population of another animal that was preying on herbivores. When the starfish disappeared, its prey grew out of control and ate all the herbivores. This caused seaweed and other plants to grow out of control, exhausting several key resources faster than the ecosystem could naturally replenish them, until the tide pool became a deadzone.

The California Monarch is the proverbial (and perhaps almost literal) canary in a coal mine. When the canary dies, sad though that might be, that is not the tragic event. No, the real tragedy is yet to come (when the mine blows, or you all suffocate on methane).
So though your question might be honest, it is likely to cause one to wonder, "where the hell have you been for the last ten years?" and irresponsibly hit the down button.
Its one things for a species to go extinct unable to evolve to the ecosystem. Its a totally different thing for a perfectly evolved species well integrated into an ecosystems life cycle to be eliminated by Human intervention.
We don't completely understand the effects of such mass extinctions going due to human actions. Mostly they are going to be bad.
Thing of this you need a range of insect species for pollination. Not just to product food, but even to maintain the existing population of trees. If you can't product food, or if trees don't grow. Eventually it will be our turn to go extinct, or at least suffer huge losses in population.
