Honeybees, Bumble Bees, and now Ladybugs-- they're all going on strike

Scientists are asking children, adults, families, educators and everyone from two to 102-years-old to join a citizens-science group to help our ladybugs.

Ladybugs were once one of the most common bugs found across the U.S. and Canada. Controlling pests that attack farm harvests, balancing the ecosystems in forests and fields, their industriousness is an important part of the ecosystem.

During the past two decades as invasive look-alike ladybugs expanded their territories and pollution and habitat loss have crowded them out, species of Native ladybugs began vanishing and the invasive species began increasing. These include the multicolored Asian ladybug, checkerboard ladybug and the seven-spotted ladybug.

The larger, rounder multicolored Asian ladybug had been introduced as a biological control for scale bugs then mass produced across the lands. It even eats ladybug larvae. The checkerboard ladybug, which is small and yellow, hitched a ride from Europe through the St. Lawrence River in the 1960s and has since been traveling steadily southward. The seven-spotted ladybug, also from Europe, came to North America in 1956. Its population extended its range as the Native nine-spotted and two-spotted began disappearing.

“This has happened very quickly and we don't know how this shift happened, what impact it will have, and how we can prevent more native species from becoming so rare,” said John E. Losey, Cornell University entomologist.

In June 2007 the Lost Ladybug collaborators, headed by Losey, received a $2 million grant from the National Science Foundation to expand the program throughout New York and extend it nationally. Their goal is to use citizen science to bring more participation in the search for the bugs. The ladybugs are collected into viles with twigs and drops of water. The date, time and place they were found are written down. The discoveries are placed on a gray square and their pictures are taken. Digital images are sent to the projects website, or color prints can be mailed to the university. The ladybugs are returned to where they were found.

The database will help scientists understand the shifting changes on earth, help farmers with crops and further understanding of rare species and the ecosystems in which they live. There are more than 5,000 species of ladybugs around the earth. About 450 are Native to North America. It’s not yet known if the new species inhabiting the continent will serve the same function or favor the same habitats as the native species.

In turn, youth will learn about the place of the ladybug in the community of nature and the importance of biodiversity and conservation for the web of life through hands-on participation in research. Educational materials, books, collection viles and nets are provided through Cornell University.

The project's website will post instructions for finding collection sites, making nets, photographing ladybugs, submitting data and uploading photos. The website will also offer an automated identification feature to provide people with real-time feedback on species that have been collected. Ladybug lore, myths, songs and culturally based stories are being posted to explain the relationships between ladybugs, pests and our food.

As of this year, more than 3,000 ladybugs will be in the new data display sent in by hundreds of participants across the U.S. and Canada.

    • I buy ladybugs every year for my vegie garden,one year I found out that the 8 year old boy next door was killing them whenever he got one. I was soo pissed off. And then I told him a story that my familys gardener told me when I was 6 about the ladybug and the boy would bring them back to me and I would have him put them on my plants. We have to tell children about how great these bugs are and not to kill them because they serve a porpose in this world.

    • i used to buy ladybugs by the pound to keep my greenhouse and garden free of white fly and other bugs. the ladys came frozen in the mail and woke up quickly when warmed up. they do bite when starved and when they swarm in large clumps but it is hardly worth notice.

      Quite a few still in North Carolina; ladybugs and Monarch butterflies.

      Hopefully this is all a coincidence (ladybugs and bees) and not us missing the boat on a very important message and subsequent change from nature.

    • i applaud everyone who takes up a cause like this "save the north american ladybug" campaign, whether it's dolphins, tortoises, polar bears, ect..

      i'm all for reducing pollution, going green, and efficiency, but when it comes to these causes, i say let darwin decide - survival of the fittest. there is reason and cause for the fittest to survive, and taking up the cause for a deteriorating species just never made too much sense for me when another one was taking it's place. my reasoning is that if 98% of the problem is the human population, how are you going to stop the deterioration? government and citizen protection can only do so much before the species moves to the zoo.

      so i'll go my way and you go yours. that way the fight for the survival of the fittest will be fair. you never know, maybe one day the north american lady bug will lead a revolt against the asians and europeans just when the intruders thought they were weakest...

    • this sounds like a great piece of creative writing. its so hard to read this and take it seriously; you cant shake off that quaint mental image of ladybugs.

    • I didn't know that there was a difference between the native nine spotted and two spotted lady bugs, and non native lady bugs. I recently released a normal looking lady bug but from my kitchen (the ladybug must have come in through the open sliding glass door.)

      When I think about it I do see far fewer ladybugs than when I was little. I grew up in the Bay Area in California. I remember seeing so many different kinds of bugs then! I remember liking the red lady bugs but not the greenish ones as I determined the greenish ladybugs bit. Now I live in Vancouver, Washington and it seems that over the years I have seen fewer and fewer ordinary ladybugs indeed. I will participate in this study, follow the study instructions and send a picture if I see any ladybugs.
      I hope people will take the invasion of introduced ladybugs species seriously. Losing our native ladybugs is unacceptable. Pretty soon all of the continents around the world will have the same boring invasive species. That's what follows in the wake of human overpopulation! I hate the Duggars!
