urbpan | Hawaii Picspam! Part two: Urban Nature (but not birds)

I took so many pictures of birds that they'll get their own post. Here's some other urban nature of Honolulu:

This big black bumblebee was in a stupor on the sidewalk. I saw others later in the day looking more lively (and harder to photograph). Anyone know anything about the big black bumblebees of Honolulu? Chances are pretty good that they were introduced from somewhere else.

anais2 put me on the right track with this one. It's a carpenter bee, and I'm pretty sure it's Xylocopa violacea, a European species.

This fern was actually in a landscape planting. There are lots of them around. The dimples on the tops of the fronds seem to correspond to the sori (spore bearing parts) on the undersides.

These Indian banyan trees (Ficus benghalensis) are so amazing to me. Apparently the symbiotic wasp that associates with this tree (all figs associate with wasps to produce fruit) was introduced along with it--I found fallen fruit around the tree. This one is wired for electricity, too.
