Butterflies of Fort Sherman, Panama

I will no longer update the butterfly post on The Twitching Sailor; please go on the link provided to see the new species I am continually adding:


All of these butterflies have been seen in the Fort Sherman/San Lorenzo area. If anybody sees errors, or knows what the 'unknowns' are, please leave a comment. Thanks in advance for any help.

Fritillary. The closest I found was Gulf Fritillary, but it seemed a bit different because the images I found didn't have the wavy black lines next to the black dots with the white spot in them.
Black-banded White
I couldn't find an ID for the Hairstreak in the three photos above.

Zebra-striped Hairstreak. It's about the size of a quarter. I saw flashes of electric blue when the wings opened but I'm not sure how extensive the blue was. You can see the color in the last photo where it is barely showing on the back of the butterfly.

Here is a 14 second video I took of a Blue Morphos Butterfly. It's hard to tell in the video, but this butterfly has a wingspan of 5 to 6 inches. It's big and beautiful:

Very large, fat caterpillar.
Large skipper, about 3 inches across.

Variable or Grey Cracker?

I have told you about the giant, electric blue Morphos butterflies that 'bounce' around in the forest.  I think I told you to google them because I couldn't get an image and had never seen one land.  I have seen two of them land since being back in Fort Sherman.  Yesterday I was able to get some good shots of one, but only with the wings closed.  It landed on the asphalt of the San Lorenzo road where some fruit had fallen and it was eating.  It opened it's wing a few times, but every time I tried to catch it with the camera, its wings were already shut! On one of the photos, you can see a sliver of blue and it will give you an idea of their color. There are about six inches across and even though I see them everytime I'm out, I still am amazed at their beauty.
 Above and below:  Ringlet Euptychia of some sort?

Little Banner
An Alana or a Veined White-skipper?
Tropical Checkered (above)
I have identified the above as either Euptychia mollis or Euptychia westwoodi. Corrections or discussions would be appreciated so please leave a comment if you can add something.

The best I could do with this one is a Metalmark of the Detritivora species. Apparently there are a lot of ssp. I couldn't find an image exactly like mine.

  1. I am very impressed by the beautiful butterfly pictures! I love butterflies. Maybe we will get to the WAP in April to see them this year.

  2. Thanks, Raves. Knowing you as well as I do, I can guarantee you won't be so enthralled with the 'bugs' I'm going to write about next. I should have started writing already, but I'm still doing laundry (every bloody thing on the boat!) I thought I might still have a chance of talking you into coming for a visit, I'm sure the 'Seed Tick' post will kill off any slim chance of that!
