Calligrapha rowena? - Calligrapha rowena
Edgett's Landing, Albert County, County, New Brunswick, Canada
June 25, 2010
I think Calligrapha rowena is the likeliest. Can anybody confirm or suggest what else it might be? Photographed on a rock in the intertidal zone, but likely blown in from the forested area on top of the cliff. Image taken in the afternoon.

Still Learning
Trying to learn how this site operates, so please excuse my likely naive question. What does it mean when you say "Moved from ID Request"?

Thanks,

Ron

I moved your shot from ID Request to the genus Calligrapha.

If you have more questions, don't hesitate to ask. We're here to help!

not sure if it's possible to tell w/o host info
in this genus, identification relies primarily on male genitals and host plants

Wow, very fast reply! Thank y
Wow, very fast reply! Thank you. Unfortunately, host plant information was not possible in this case. Any idea what other Calligrapha species occur in New Brunswick?

a total of ten spp. in NB
alni, alnicola, confluens, ignota, multipunctata, philadelphica, rowena, tiliae, vicina, & virginea, according to(1); about a half can be excluded, i think -- but that wouldn't be good enough :(

best guess, rowena; can't rule out ignota
hope Dr Gómez-Zurita chimes in

Calligrapha
looks good to this non expert. Getting to species might be tricky, though, and might require knowledge of the host plant. See comments here:



Let's see what the experts have to say.

Thank you for the link Ken.
Thank you for the link Ken. Looks like identification to the species level may not be possible given the host plant could not be determined.
