Healdsburg, CA Posts: 356 | I've put up the larva before but not the pupa. The pupa is commonly found attached at both ends to stones. Occasionally it is found attached by the front end to a large stone. It is usually found in slack water. The common name is White Miller. | |

Healdsburg, CA Posts: 356 | Roger, Several caddisfly pupae have forked terminal processes. Some that come to mind are various Leptoceridae species, some Uenoidae species and some Odontoceridae. Anyway, it's always fun to find something like that. Mark | |

Novi, MI Posts: 2608 | Hey guys...How about walking us through the process after this stage? I'm looking at the pictures where we see the underside of the insect and was wondering...Does all of this continue to the next stage? What I mean is, the wings here seem short...Does the green abdomen drop off or does that remain with the adult? Maybe this specimen isn't "that" close to "hatching"... How about a walk through?

Healdsburg, CA Posts: 356 | Spence - The abdomen remains with the adult. The wings are somewhat shortened and folded and stay that way until it becomes an adult. You can get an idea of how it works by looking at the exuvia left behind when it transforms from pupa to adult. http://www.troutnut.com/topic/8669/Neophylax-larvae-and-pupae Mark | |

Site Editor Royse City, TXPosts: 1350 | Hi Spence- I sense that your question relates primarily to the disparity of the wing/abdomen length, between the pupal and adult life stages. With regard to only that specific issue, the abdomen remains essentially the same length in the adult. However the wings of the adult get "inflated" through their venation at time of emergence, such that the longer fore wings end up reaching well beyond the end of the adult abdomen when in their resting position. Hope this helps. | |

Novi, MI Posts: 2608 | Yes it does. Thanks to both of you. 13mm is a pretty fair sized caddis. Spence | |
