I'm only talking about the bugs that were recently and abruptly removed. And some people (like myself) do use bugs as "decorative furniture". Yes, there are rare bugs that are indeed usually displayed as "trophies". I'm talking about roaches (as well as ladybugs and bees, but mainly roaches), one of the most common bugs in the game, and a very useful bug for house-design purposes (example: placing them around food, giving the impression it's been sitting out for a while).

And regarding ladybugs; I currently use the lava-themed house. And I have a section that's full of grass, water, and wildlife. And I use certain bugs to help depict that (ladybugs being one of them).

Those are just a couple examples as to how some bugs are in fact useable for house design purposes.

Edit - Okay so I didn't realize ladybugs were still spawning. I just assumed they'd have been removed. Any chance you could put roaches and bees back for a limited time at least? If ladybugs are still spawning despite this recent incident, then why are bees and roaches gone? (As I recall, this over-spawning incident happened once with bees, but that was only because someone tweaked the code wrong, and their value was hugely nerfed anyway. And I don't know what happened with roaches, but they had been working fine for a long time, so.. c'mon!)
