Butterflies
American Copper, Lycaena phlaeas. Another name for them is Flame Copper. They are small and vivid.Common buckeye, Junonia coenia.

These develop without pollination; they are parthenocarpic. I mean the…

Systems of change
“[…] it is often not easy to assign insects to precise categories because there are so many species and their morphological, behavioral, and genetic differences frequently tend to overlap or intergrade. Often the best we can do is estimate degrees of relationship and/or distinctness and assign them to hypothetical groups as information becomes available. As…

Back 40 Grasshopper
Less than half an inch long, this little grasshopper leapt out of the Back 40 greenery when I started to water and clung to the plastic (yeech!) fence.

Furman St. Cattails in Summer
Back in March I noticed some improbable cattails growing from the roof of an old garage on Furman Street, underneath the Brooklyn Heights Promenade. I recently walked by again, both underneath and above.I think there might be some pragmites up there as well.
