Native Ladybugs Getting Scarce

There seem to be not nearly as many Ladybugs attempting
to invade our house this Fall.
In previous years they descended on us by the hundreds,
covering the window screens looking for a safe winter home.
Why not as many as in previous years? We don't have a clue.

The distribution of native Ladybugs across the North American Continent
has changed significantly over the last two decades.
Many species have become very rare.
The invasive species from Asia have become abundant.
Cornell University has a "Lost Ladybug Project" to be viewed at

At a sub-link you will find a picture of "C9".

This Ladybug - C9 - Coccinella novemnotata,
(Also known as nine-spotted Ladybug)
is the New York State insect.
