	Duration: 03:07 minutes Upload Time: 07-03-27 16:04:45 User: jcmegabyte :::: Favorites
Description: A short documentary showing Catocala junctura 1st instar caterpillars. These tiny hyper-active larvae are about 3/8" long and move with an interesting, almost comical, fast looping movement. High magnification video shows close-up details of the caterpillar and its feeding on the Willow host plant. The soundtrack is "Gypsy's Theme" by Technician (from the "Memories" CD).Much more free video, photography and documentation is available at http://lepidoptera.jcmdi.com/index.html. The Hi-Res version of this video is available on DVD. Visit http://technician.jcmdi.com/lepdvd01/lepdvd01.html for details.

sigma1920 ::: Favorites Excellent shots, very informative. They walk like measuring inchworms. Semilooper? 07-03-27 20:41:10 _____________________________________________________
jcmegabyte ::: Favorites I'd have to call them full-on loopers. They're very loopy indeed! In fact, they don't appear to move in any other way - what few legs they have are tightly grouped at the front and rear of their body, so that crawling in an undulating fashion like most caterpillars is probably impossible. 07-03-27 22:43:49 _____________________________________________________
sigma1920 ::: Favorites Thanks for taking your time to share the detailed info. For some reason, I like watching caterpillars. I thought loopers are mostly larvae of Geometridae moth. And Catocala underwings belong to different family Noctuidae. Don't you say semiloopers? I am wondering if this term is old-fashioned or japan-local. According to a booklet on moth caterpillars, semiloopers have two more legs than loopers at the rear end. 07-03-28 04:08:07 _____________________________________________________
jcmegabyte ::: Favorites I must have replied to this 2 or 3 times already but for some reason it won't post. Perhaps it's going directly to the reply-ee? Anyway, you are probably right about loopers vs. semi-loopers - that's a new term to me and I was only trying to be funny about the "loopy" comment! It should be interesting to see if these cats loop the same as they get larger. 07-03-30 11:36:02 _____________________________________________________
sigma1920 ::: Favorites This is the first time I saw the actual locomotion of Catocala caterpillars. So, thank you! BTW, I like this title "Catworms!", though it took a while to sink in. 07-03-28 04:09:54 _____________________________________________________
bugvision ::: Favorites those close ups are cool! how did you get them? was that the microscope you used in the other egg hatching video? 07-03-30 11:21:58 _____________________________________________________

jcmegabyte ::: Favorites For these high-mag shots I used a jeweler's loupe, held-up to the camera lense. Surprisingly, it works, although the depth of field is very shallow. 07-03-30 19:16:48 _____________________________________________________
