ID pointers: A brown and intricately marked Pug. The dark discal spot on Brindled is usually much smaller than on Oak-tree and has a thinner-looking and slit-like appearance. and beyond this central dot there is usually a pale area, but normally far more prominent on Oak-tree Pug. The outer central cross-band is pale and has a series of fine black streaks and wedges projecting inwards. There are two parallel ‘dashes’ beyond the discal spot that project inwards. There is usually a small kink in the sub-terminal line near the apex which distinguishes it from Golden-rod Pug.
