Hydropsyche (Spotted Sedges) Caddisfly Pupa
View 8 PicturesSeveral users have interesting comments in the discussion of this specimen, but this observation by Creno is especially good:
Also, this is what I would call an "immature" pupa. The wingpads of caddis pupae darken to nearly black as the enclosed adults near emerging. The darkening is the developing adult wing inside the pupal wing pad (
The wing pads on this final instar
Baetidae mayfly nymph are extremely dark.
Wing pad: A protrusion from the thorax of an insect nymph which holds the developing wings. Black wing pads usually indicate that the nymph is nearly ready to emerge into an adult.). The ultimate coloration of the adult wing is not very apparent in most pupal wing pads (

But dark pupal wingpads are a good indication that the emergence will occur very soon, likely that day or so, and that the adult parts are sufficiently developed within the pupae to make a species determination from the specimen, particularly if it is a male.

shad run/ Delaware and tribs 3 Replies »Last reply on Jan 19, 2015 by
Sandflyat risk of offending the purists... can anybody help me with timing the shad run on Delaware and/or tribs? I will want to wade so has to be upper reaches I guess. I am told lower Neversink has a healthy shad run? and while I am asking, does the striper spawn more or less coincide? is there a time of year when one is likely to catch shad/stripers/trout all on a fly? I have caught smallmouth/juvenile stripers/trout in same stream/same day once before (Croton River); but I am told there is no longer a viable shad run there, as several years ago they cut off all flow from the dam upstream.
