OK....I should have taken a picture...I will from now on

Can you guess what this was from my description please? It was in the mouth of a fish..just taken it....on a stillwater.
length .... about three quarters of an inch
Proportions.....One fifth head, four fifths long tapered body...flatish... elongated triangle shape of body.
Head colour....brown on the back of the neck with wee stumpy "golden ish" legs below,,,head generally golden in colour.
Body.....segmented effect....dark blue dun on top, light blue dun below. "Rib" looked a very light grey.
That's the best description I can give I'm afraid, but maybe someone can get it from that !!
Thanks........
