I Am Become Death, Destroyer of Aphids
Sometimes seems that everything you see is an invasive species, even a ladybug in my yard that turned out to be an Asian species originally brought to America for pest control.
But this little ladybug, fierce and ferocious (if you’re an aphid), is not the same species! Have I finally found one of our native ladybugs? Alas, no, it has two spots too few. The seven-spotted ladybug is closely related to its American cousin the nine-spotted ladybug, but the nine-spot is rarely seen these days. The seven-spot is native to Europe and, like the Asian beetles, was brought over to the States for pest control and then established itself in the wild. This one established itself on the petals of my purple coneflower. But the aphids are on the roses! The roses! For the love of Sammy, the aphids are on the roses! Ah well, I’ve gotten a little disoriented in foreign lands myself. |

Who Am I?
I'm no lady, at least not yet. Who am I? |

Who Am I?
Some call me bug, though bug I am not. Some call me bird, though bird I am not. Who am I? |

Lady Larva
Ladybugs might not look the part of the predator as adults, but they certainly do as larvae. Is there any other creature that goes from looking so fierce to so cute as it ages?

Pupal Vestments
Ladybugs go through several stages before they become adults. They hatch from eggs into the larval stage, where they look more like miniature alligators than cute little ladybugs. After a couple of weeks they enter the pupal stage shown here, where the larva sticks itself onto a plant and the skin splits and protects the pupa underneath. During the next week or so the pupa metamorphoses into an adult and finally emerges as the familiar little beetle we all know and love.
This particular ladybug is a multicolored Asian lady beetle, which is not native to the United States. Ohio State's extension office has a nice writeup on this (often deliberately) introduced little predator. |

Our Newest Predator
After finding a ladybug pupa attached to a leaf on one of our daisies, I checked it every day while taking Ellie out for her walk. One day I noticed the pupal shell looking a bit dried out and the reason slowly dawned on me. I grabbed Ellie's floppy ears and shouted "My ladybug hatched! My ladybug hatched!"
Ellie didn't share my excitement since this involved neither food nor hedgehogs, but I got even more excited when I realized the newly minted ladybug was on the other side of the leaf, waiting for its wings to dry. I decided to hold off on pictures and took Ellie on her full walk, which in hindsight was pretty risky, but it all worked out. The ladybug was still there when we got back and I ran inside to get the camera and took, oh, let's just say a few pictures. When I got up to let our cat Emma back inside, I returned to find the leaf empty. Our yard's newest predator had taken flight, but not before I got some nice pictures. In this one, the ladybug on the left waits with wings outstretched to dry. On the right is the orange and black shell from which it just emerged. |

A Change of Plans
I brought my camera and macro lens into the backyard with the hope of photographing some of the little greenish-white spiders that live in the coneflowers. They weren’t cooperating by posing on cones at the edge of the patch, so I started puttering around the yard.
While trimming one of my favorite rose bushes, I noticed this ladybug was on the underside of one of the leaves. I rescued it from the clippings and put it back on a rose petal. It was a real eye-opener when I looked at the pictures later. I had always assumed the black patches on the white middle section were its eyes, and was surprised to see its real eyes just below that section, two compound eyes much like a fly’s eyes. |
