Coreopsis verticillata 3, Whorled tickseed

Coreopsis verticullata - Whorled Tickseed. Always popular with bees, the Coreopsis group, as a whole, is widely planted, tough, and long bloomer, but reasonably rare out there in the wild, with some of the planted species not local to the mid-Atlantic. Should they be planted then. Where are the limits?

Helicoverpa zea - Corn Earworm - According to Wikipedia its the second most economically damaging insect pest in North America, chewing on a wide variety of crop plants. This most certainly is true, but it also not a bad looking animal when viewed close up.

Cornus florida, 2 flr.,Dogwood, Howard County, Md,

The dogwood of the people. Cornus florida. Planted widely. Formerly forming a subcanopy of white in the spring in much of the eastern forests. Then, the Dogwood Anthracnose comes and most of those interior woodland dogwood are now gone and dogwood is largely confined to edges of woodlands or plantings in the open. Specimen and photo by Helen Lowe Metzman.

GENITALIA! In this case the beautiful genitalia of Cosmorrhyncha one of the bitty moths in the family Tortricidae. Thanks to John W. Brown for supplying the slide. See previous picture for more details. For some reason this makes me think of biker gang insignia....

This is a shot of a Tortricid Moth from the Cosmorrhyncha genus ... the genitalia and perhaps the abdomen, though this is not absolutely clear to me. The slide was given to me by John W. Brown from the natural history Museum at the Smithsonian as an experiment to see if I could get a good shot of a slide mounted specimen.

Cotesia congregata - a little parasite of caterpillars. This one is from Karen Kester's lab in Richmond where she and her gradstudents raise them and discover things about the host (Sphinx moths I believe) parasite relationship. Photo by Greta Forbes.
