It’s another day of sprinkle and rain. The last few days have been that way. I got out briefly on Monday and Tuesday. Yesterday it rained off and on and it was on every time I thought about going out. Gene and I got a soaking when we went to watch Yo and Dan of Jacana pull away from their slip and head for their transit. They are on their way home to Oz via Galapagos and the Societies. I look forward to looking in on their blog to see what Galapagos photos Dan will post.
I have their blog posted under "Sites to See" on the left hand side of my blog. It's, Jacana's Yarns.

Gene went into Quatro Altos to grocery shop and get a propane torch. I’m staying aboard today and trying to write and research. Maybe today I’ll actually do that rather than play computer games like I did yesterday.

I’ve already found that one of the giant “dragonflies” I saw is a damselfly: Megaloprepus caerulatus. It is a beautiful insect to watch and looks like an ‘X’ when it flies. It’s flight is slow and it seems like a lot of effort goes into it. I thought the body was 5 or 6 inches, but apparently it’s only 4 and the wingspan is 7.5. Still seems bigger than 4 inches to me. On Monday, I was able to get better pictures of it. The photo I posted is the clearest, but it doesn’t show the beautiful blue in the wing like some of the fuzzier shots do. I tried to get it in flight, but the shots aren’t worth posting. This damselfly would even grab the attention of people who usually pay no attention to the natural world at all.
I knew there were Damselflies and Dragonflies, but I never did any reading on the subject. Now I think I get the difference:

I have photos of both Damselfies and Dragonflies from various parts of the world and when I am not being overwhelmed by new bird species, I will be very happy to spend time on them. If I spend too much time on them now, I’m afraid I’ll be like the old ichthyology professor who forgot a fish every time he remembered a student’s name.
I saw a Hummingbird Moth on Monday.

    You are indeed my dughter ! During the Stanford Summer Field Geology Mapping course, I acquired the nickname "Bugs" because it seemed to the other students that I had a greater interest in beatles, grasshoppers, moths & butterflies than in rocks !
