The original photograph is at flyfishing entemology.com. the pictue is titled caddis home. Troutabout- If you are referring to FlyfishingEntomology.com, I'm not aware of any file titled caddis home on my site. However, I did Google/Images "caddis home" and found the following photo from Michelle Mahood's gallery: http://www.pbase.com/michellemahood/image/24877105 Is that the photo? | |

| Mercer Island, WA Posts: 483 | Troutabout- No problem. I would guess the photo is of a cased Platycentropus larva. As to which species of leaf was used in construction of the case, that question will need be answered by someone else. | |

| Posts: 20 | Roger:you are the man! Thanks for your timely responses. I entered a fly swap challege and was given green artificial lei flowers,tan jute and some black yarn to tie with. I just tied two of them and wanted to know what they imitated. Is this a common species? Where in the US are they found besides CA ? | |

| Mercer Island, WA Posts: 483 | Roger:you are the man! Troutabout- Well, that stands to be seen. There are others on this site who know much more about caddisflies than do I. As to where they are found, to the best of my knowledge, only in the East and Midwest, where "they are able to thrive in a in a wide variety of habitats, including stillwaters and warmwaters" per Gary LaFontaine. | |

| Posts: 141 | The source I have (although I admit I didn't do an exhaustive literature search)says Platycentropus is only found in the East. Further, although I realize details are hard to see on this photo, this caddis appears to be lacking the identifying feature of Platycentropus--prosternal horn extending to mentum of labium. It just looks like Limnephilus. Limnephilus is one of those catch-all genera. My ID may change in a few months when I start working with some new keys, but it's my best guess for now. The leaves look like they may be from duckweed, but the pictures aren't very clear. It looks like the caddis from your northern CA post, TROUTNABOUT. Just a tidbit: The family name "Limnephilidae" can be translated (fairly accurately) as "'likers' of standing water." | |

| Knoxville TN Posts: 49 | Schmid lists Platycentropus radiatus from Nova Scotia to Manitoba, my records also include AL GA NC SC TN VA northward. don't have records on P. amicus or P. indistinctus but Schmid lists amicus from Quebec to Alberta and indistinctus from Newfoundland to Ontario. all three are as others have said are distributed in the eastern half of the continent so I'll chime and say I bet that ain't Platycentropus from CA. but the prosternal horn character is the one to look for. | |
