IDs please

I'm now running behind in my catches - these were from Saturday night. The first one was easy but a suprise, a Scorched Wing, I think the othe one is possibly a Large Nutmeg although there seems to be a hint of a shoulder streak, I think I have a cadis fly and the final one I can't find at all.

    I think second pic is Rustic Shoulder-knot and last is Spruce Carpet

    HI Darren, definitely a Large Nutmeg. The Carpet is likely to be Grey Pine as the basal colour of the median band is chocolate brown rather than greyish as in Spruce. The dark lines around the "cells" in this median band in Spruce are also darker and more distinct.

      Hi Peter, in the concise guide it only shows RS-k as having the 3 whitish dashes on the leading edge, the 2 Large Nutmeg images haven't got these. this was the obvious difference i was going on. With this example having a slight basal streak too, i was convinced. Whats the best way to separate these 2 species? I've always recorded ones like this as rsk.

      OK, the easiest way to make sure it is a candidate for RS-K is to look for the black basal dash. That's the main diagnostic I use. The LN lacks this dash, or at best it is indistinct. If you have Skinner, you can see your white dashes in the LN. The LN also has paler areas just before the termen, up to 3 and you can see a paler area in the image, otherwise it simply looks like one (but that doesn't help you or others)

      If it helps Darren, LN also has a moderate "W" pattern towards the inner end of the outermost cross line and the outer central crossline in LN is far more scalloped than RS-k though you can't easily see that in this specimen. The sandy marbling in LN as for this specimen can be quite distinctive as well.

    ...and for what it is worth, the caddis is one of the few "easy" ones, Mystacides longicornis.
