Global Insect Population Decline
![US](https://depts.washington.edu/i2sea/images/flagpedia/US.png)
There's an entire subforum on here about ocean acidification and the ramifactions that has, but equally important and significantly less talked about is the decline of insect populations. Maybe it's because we just don't like bugs as much as we like sea turtles, but the ecological impact is going to be severe.
Personally, the contrast between my childhood memories and what I see now is astonishing. A few years after I moved to the house I live in now, around 2007-2008, I can remember huge amounts of black swallowtail and cloudless sulphur butterflies, and keeping some of the caterpillars in a jar inside to watch them pupate and hatch. But this year I can only remember seeing maybe three or four swallowtails, and only a couple of the cloudless sulphurs. We would get swarms of lovebugs in October, literally thousands in the air and of every available surface, but I only saw a few handfuls last year. I have only seen one carpenter bee so far this spring. We don't have to clean the windsheilds or grills of our car anymore. There are even fewer roaches and palmetto bugs at night.
I know this is a global issue, but the personal impact is just so stark.

I'm in a subtropical region of the US, what is it like elsewhere?

You make a really good point about the impact on the insects. They’re a really important part of ecosystems, so the effect that their decline will have spans even larger. I personally am not as interested in insects as I am in other organisms, but they play a huge role in food chains and things like pollination. The decrease in diversity you’ve mentioned also sounds really concerning too, with much less of the insects that you were used to seeing before.
