Where I used to live: Manhattan |
|
 |
|
|
Lower Manhattan with the "tribute in light", seen from Brooklyn. For my first year in New York, I lived a few blocks south of Ground Zero, i.e. near the rays of blue light you see in the photo.

The remaining years I lived near the Empire State Building.
The colors of the lights on the ESB are different every day. I thought this combination was particularly pretty, especially with the way the sky looked that very moment. |

I was extremely lucky to find a house that has a garden in the back for the use of all tenants, especially right in the middle of Midtown Manhattan, where thousands of commuters pass through every day. This is where I sometimes had breakfast and dinner in the summer.

Collecting in Germany |
|
 |

Obviously, collecting Monoctenus
is much easier. By the way, this was one of only three days of nice, warm weather I had in three weeks in Germany. |
I enlisted my mother as a parataxonomist.
She managed to collect some Monoctenus without a net. |
