Ok here my attempt to explain.
Lady Bugs (of most type of the species and these look american) are benificial.
1. Lady Bugs eat aphids, aphids eat plants, so you want lady bugs arround thats why you don't kill them.
2. If you have alot of Lady Bugs like any other spieces other then humans then you have alot of food arround for them. So therefor you have alot of
aphids in that area.
to go further..
To have alot of aphids you need alot of plants...
Did you notice alot of rain this year? Yep the Storm systems are further north this year because of the sea temps are cooler in the tropics and
slightly warmer in the north. see:
www.nhc.noaa.gov...
This is causing more rain across north america then normal. In Colorado where I live we are 1 inch above normal for rainfall. I am sure this is
going on elsewhere.
So we have plants getting more rain and plenty of sunlight and lots of CO2 that means higher plant growth. Basic plant biology there.
That means populations of insects will rise both good and bad. It would be intresting to see if there are other stories like this going on across the
country it would prove this theory to some degree.
