A male alate or the winged reproductive form of the normally wingless ant group. The species is currently unknown, but we have it sent off to someone for identification.

20X Lens Tests. I am posting 3 pictures taken with a "new" 20X Mitutoyo Plan Apo Infinity Corrected Long WD Microscope Objective attached to an old 200mm Pentax lens. This allows me to start getting into some extreme stack territory. That said this lens new is over \$2000.00 U.S. However, I found a scratched one on Ebay for \$300.00.

A bee that has not been seen in Maryland for over 100 years. Protandrena abdominalis. And...still has not been seen in Maryland for 100 years. This specimen actually came from Texas where I was visiting my kin (but not so secretly also collecting bees).

This little red bee was collected on spotted beebalm. It seems to be the only species of plant, with the possibility of some close relatives being involved, that this bee finds worthy of collecting pollen from. If you Google images of spotted beebalm you'll see that it is quite the complicated and rather ornate flowering plant.

Arizona poppy pollen on Protoxaea gloriosa. Yep, the fluorescent orange Kallstroemia grandiflora, has fluorescent orange pollen and this bee loves it and becomes also fluorescent orange.

One of the best bee plants...big, tall, and simply by being a tree, voluminous in pollen and nectar resources. Black Cherry. Prunus serotina. Specimen and plants by Helen Lowe Metzman.

Meet an illegal immigrant. This is Pseudoanthidium nanum a bee we first realized was present about 10 years ago. It now is established in the NJ and MD areas, and I believe I saw records from the Chicago area last year. I have only found it in the most urban of urban areas on the riot of corrupting weeds that we always bring with us where ever we live.
