I've got an infestation. They buzz around, crawl around, and don't much bother me. I think I was told as a child that both ladybugs and crickets are a sign of good luck, so unlike some other invaders I kinda welcome them.

Are they here for the weather? They seem pretty sleepy on a cool morning. Just curious.

Ladybugs, or lady beetles, are a very beneficial group of insects; a single lady beetle may consume as many as 5,000 aphids in its lifetime.

Depending on the species, lady beetles go through at least one generation per year, with adults overwintering by hibernating in aggregations under leaf litter and other debris. Rarely, aggregations may find their way into homes in the winter. Pest-proofing a home by applying caulk and weatherstripping should prevent this from occurring.

...unless extremely objectionable, (lady beetles) should not be killed since they are very beneficial.

We love 'em, aphids all over the roses and clematis and the ladybirds hard at it too! Best year for roses for a while. We also feed aphids to the fish in the pond. :cool:

One tonight was insistent, incessant, and generally out of control. It was crawling and flying around; all over my hands and in my hair. I gave it some water.

Don't know where it is now, but the water made a huge difference. As Kafka asked, "Am I the insect imagining a human incarnation, or the human imagining an insect's?" In anycase, some water hit the spot. It was rather gratifying to watch a ladybug drink. I got out a magnifying glass and watched. They have very comical feet. ;)

Cheaper to feed than a dog! :D

I gave someone a dollop of honey in addition to the water tonight. It appears to be hibernating early, or maybe has drowned in the honey! Tomorrow will tell. I think it's just having honey fits. Cute little beasts.

Apparently the Japanese variety of Ladybug has been introduced to North America as a natural predator. I don't remember where I read this.

Ladybug, Ladybug
fly away home
Your house is on fire
and your children all gone

All except one
and that's little Ann
For she crept under
the frying pan

My lab works on them. The species that invades homes is the multicolored asian ladybeetle, Harmonia axyridis. They were deliberately released several times into the southeastern US to control pests but failed to establish.

It seams that they were unintentionally introduced via ship through the port of New Orleans and have since spread up the Mississippi. They have become important predators of the soybean aphid, also asian, which is a new major pest in the United States on its host plant. You may want to check out our web site to learn more about The Multicolored Asian Ladybeetle (http://www.ipm.msu.edu/asianladybeetle.htm) .

There's some info there about why they invade houses and about our reserach. Despite being a pest (yes, they do bite sometimes!), they do a lot of good in the bean fields.

Thanks... very informative. We do have the asian variety up here in southeastern Ontario. They seem to have done well here smile.gif

They're doing great here in Minnesota. Saw an Asian Lady Beetle Trap in the hardware store today, but for $40 I'll keep using a tissue for a while.

I've not heard of a trap. Bizarre!
