Western thrashing ant attacking insect larva. We arrived at an area of southwest Washington called Long Beach yesterday.   This morning I was out for a quiet walk with my camera; it was equipped with a macro lens and macro lighting system.   It is always fun to explore new places to see what kinds of finds can be discovered.   I had quite a bit of luck as I ended up with half a dozen pictures which I am excited about.   The one above is an example.

According to William Neill, author of Butterflies of the Pacific Northwest , the margined white butterfly used to be common throughout most of mid latitude North America.  I found this one in a very rural area of Wa...
