One of most exciting aspects of
watching wildlife is that you don’t have to be a biologist or full-time
naturalist to make important discoveries about the natural world. It’s not
unusual for recreational birdwatchers to find and identify rare or out-of-range
species, for instance, and the same is true of those who enjoy wild plants,
butterflies, marine life and all sorts of other creatures. Often all it takes is to pay attention to the
species that cross your path and to know enough to wonder aloud if something
seems out of place. And sometimes it takes even less than that.
Take the rediscovery of the lost
ladybug, for instance. That’s not really
its name, and it’s not really lost, of course; it has simply disappeared from
most of its range. The nine-spotted ladybug was once the most common ladybug
found in the eastern United States. It was highly valued for its ability to
suppress pest insects in agricultural fields. One of several dozen species of
ladybug native to the region – all more appropriately called lady beetles –
it’s the official state insect of New York. But over the last 30 or 40 years,
it disappeared with hardly anyone noticing, as non-native ladybugs arrived and
became dominant.

Nine-spotted ladybugs look somewhat
like most other common ladybugs – reddish-orange with black spots. But this one
has exactly nine spots, four on each elytra (that’s the reddish part that
covers its wings) and one spot in the middle that’s split by the two elytra.
In 2004, researchers at Cornell University started the Lost Ladybug Project to encourage the general public to
look for it. They asked people to take photographs of any ladybug they find and
post them to a website for experts to identify. By 2014,
citizen scientists had submitted 30,000 ladybug pictures but found very few of
the nine-spotted variety, mostly in scattered locations in the West. Just one
was found east of the Great Plains.
In June of that year, however, a volunteer participating in the
Rhode Island Natural History Survey’s annual biodiversity field day, BioBlitz,
found a nine-spotted ladybug at Rocky Point in Warwick. It was the first record
of the species in the state in at least 30 years, and no one knows exactly who
found it – probably one of a group of kids using insect nets to capture
whatever they could find. It took almost a year for all the insects collected
that day to be identified. When the specimen was finally brought to the
attention of the Cornell team, they rushed to the site to look for more but
found none.
So David Gregg, director of the Natural History Survey, and the
Cornell researchers hope you’ll join the hunt for the lost ladybug. June is the
peak of ladybug season in Rhode Island, so if you see a ladybug that has even the
slightest chance of being a nine-spotted ladybug, post a picture of it to the
Lost Ladybug website. The site has tips for finding and photographing ladybugs,
along with fact sheets so you can learn to identify the other ladybugs in the
area.
The best chance of finding one is probably somewhere around Rocky
Point, since that’s where the last local specimen was found. But the next one
could turn up almost anywhere, including in your backyard. So be on the
lookout.
