Lady Beetle - Naemia seriata

Lady Beetle - Naemia seriata
Hart-Miller Island/Chesapeake Bay, Baltimore County, Maryland, USA
August 18, 2007
Size: 4 mm
I found this beetle on Hart-Miller Island. It was bright yellow in the field but the color had dulled some by the time of the photograph. The body shape is elongated not round.

Moved from Naemia seriata.

Naemia seriata
It has an apical suture spot, giving it three suture spots total. Coleomegilla maculata has only two suture spots; there's a small apical spot on each elytron, which do not coalesce into a suture spot in any photograph I've seen or reference I've consulted.

The black center of the pronotum is also more typical of N. seriata. I've seen N. seriata with two dark pronotal spots, but never C. maculata with only one.

 
oops,
thanks for fixing that blunder!

 
no prob :-)
I was busy checking Naemia seriata for misplaced C. maculata when it occurred to me to check in the other direction too...

Both genus and species Info pages for Naemia were blank, I thought they used to have some text and images, don't know where it all went. So I did a quick fill-in last night, but it's far from perfect.

BTW, do you think we should do subspecies nodes for N. s. seriata and N. s. litigiosa?

 
your call,
I don't know what the current thoughts on subspecies significance are.

Normal Variation?
While examining this beetle, I thought that it was most like Coleomegilla maculata which is present on Hart-Miller Island, but there were differences that concerned me. 1)This beetle was bright yellow instead of red or pink. 2)Head was all black instead of having a triangular red or pink (or yellow) space. 3)Pronotal spots were fused. 4)There were three black spots along the suture, instead of two. --- Normal variation?

 
yes, normal variation
1) while it doesn't look the more typical pink/red, from the photo I see only hints of yellow (with a hints of some pink too), 2) black head means female while males often have most of the head pale yellow, on this and many other ladybird species, 3) fused pronotal spots is within stated variation by Gordon, and 4) All have 3 black spots along suture, although on some the aft most spot does not meet/join at the suture, thus leaving a separate spot on each elytron. A quick review of the current BGuide images shows them apparently all separated. But your arrangement is still allowable. Still, you astutely observed many differences that most never notice.


so this still looks like "a typical" Coleomegilla maculata to me. And there's really no other choice according to Gordon's ref., unless something was recently introduced (but I think not in this case).

But keep posting to BugGuide! I was more intrigued by your "aberrant Seven-spotted Lady" and the others you observed. There are far more possibilities for Coccinella species in our area (many yet to be posted on BugGuide). I couldn't initially find an alternative to Coccinella septempunctata, but I may make another attempt when time permits.

Coleomegilla maculata - Spotted Lady beetle
only one like it. see info page here

A ladybird
I'm not sure which one though? Boris might know.
