C. kuwanae for Pennsylvania - Chilocorus kuwanae - male - female

C. kuwanae for Pennsylvania - Chilocorus kuwanae - Male Female
Penn's Landing, Philadelphia County, Pennsylvania, USA
August 16, 2009
Size: female 5mm; male 4.2mm
Hundreds of these Chilocorus kuwanae lady beetles were on a scale-insect-infested birch tree. I literally could not look six inches from one without seeing another.

The larger female is facing to the right; the smaller male is facing to the left. They mated but I wasn't able to photograph it.

Identity confirmed by the Lost Ladybug Project at Cornell University.

Chilocorus with flattened or rectangular dark-red spots aft of middle - am I seeing things, or are they really Chilocorus kuwanae?

Black Ladybug with Red Spots
I know this ladybug very well, but I can't remember the name. We had an infestation of Cottony Maple Scale, and these were the biological saviors of the day! Great photo, by the way. I tried to photograph some of ours, and they were so small and so black, and they liked to move quickly. I know that www.lostladybug.org would a) love your photos and b) help you identify.

 
Lost Ladybug ID'd them!
Following your advice, I sent the photo to lostladybug@cornell.edu and got a response within 24 hours confirming the identity as C. kuwanae.

My beetles weren't too active (except when the males were running around and mating with all the females!) and photographing them wasn't hard in that sense, but the glossy blackness flummoxed me. I asked for advice in the Photography forum and got a lot of information. This photo is already improved by a Photoshop tip that I got.

I love this site :-)
