    I've been watching some gulf Fritillary caterpillars eating my passion flower vines this week. They went from 1/2 inch long to about 2 inches long in a few days. Today I noticed a few of them "missing". I found them disguised as dead leaves. I hope I am able to capture the emergence. D-200-300mm f/4 and nikon PN-11 ext. tube.

    Caterpillar has just glued itself to the vine....

    This one looked like the first shot this morning, you can see the remnants of feet and the wings forming...

    Anyone know how long before they emerge?
     
  2. Scott,

    I checked my reference books and I couldn't get a definitive answer, somewhere between 7 and 14 days. I planted a red passion vine this year with the hopes of attracting fritillaries. So far, I have seen two great spangled fritillaries. I am hoping that the ants haven't eaten or destroyed the eggs.

    Thanks Crystall. I have 4 chrysalis's now. 2 from today and the other 2 about a day or 2 ago. There is also another batch of little ones, the passion vine might not make it!
     
  4. That´s one crazy looking caterpillar for sure :smile:

    #2 is very nice (what ever it´s called in english... cocoon?)... Looks pretty much ready to emergence, looks like there´s antennaes too...

    Thanks Jukka, The cocoon pictured ,I'm not sure of when it happened. The caterpillar shed it's skin this morning and looks almost exactly like the other cocoon. I'll be checking them everyday.

    Thanks David. Why the big lens? On these I could have used any macro lens as these subjects are not going to move. I use the 300mm and extension tubes to give working distance on more skittish creatures. I don't have a "macro lenses", just the 300 and ext. tubes. The 300 mm by itself is good for closeups on larger bugs like dragonflies and butterflies.

    Thanks Torben. I've been checking them every day, they should open next week. Hopefully I'll catch the emergence.
