Living here in suburbia the lack of wildlife is obvious when compared to my parent's house out in farm country. I've gone years without seeing lightning bugs here while at my folks you can see dozens at a time every summer. I'm sure pesticides play a part, but so does the fact that there are virtually no large clumps of long grass. The beetles hide down in the grass during the day and lay their eggs there. No tall grass, no lightning bugs.
All that does is point out the difference between the real world and the big city. Do you really need bugs in Detroit? ;-}
That said, I got no lack of habitat here. In fact, there's a few farmers here who run hives, and one gets away every now and then and wanders over my way.
I find one, give the guy across the street a call to let him know where they are, and they'll be over shortly to coax em home.
Besides, rumor has it this is more of a cyclical thing than anything else ... kinda like global warming. It happens. That of course depends on who you listen to.
** Just fershitzengiggles, how's your local area deal with "native lawns"? That sort of thing can sometimes result in a severe frowning at least from the local ordinance police. I've got a couple acres here, half of which is natural, but it's all grass ...or a reasonable facsimile of anyway
... up by the road, and I'm sure somebody would stop by and p!tch a b!tch if I let it go back to nature.
PS ... just picked up a couple five pound bags of last season's "meadow" seed at the local farm and fleet the other day. Mixed grasses and wildflowers, certified for the area. Cost me all of $6, and should germinate fine as long as it was stored halfway decent. I'll broadcast those come spring and give em a quickie blow job (probably a better way to put that) to settle the seed to earth. I do that every few years anyway, with good results, and may be a good option for yall to check in on.
