This nice orange ruff on the front of the thorax is an aid to its identification.<\/p>\n

American Tissue Moth Triphosa haesitata <\/em>(Lep.: Geometridae) Jochen M\u00f6hr<\/p>\n

The foodplant is restricted to Frangula.<\/em>  <\/em>The adult moth hibernates – sometimes in numbers in caves.<\/p>\n

 <\/p>\n

The pugs are a large genus, many of which are challenging to identify.  This one is probably one of the difficult pair Eupithecia annulata\/oleracea<\/em>, both of which feed on conifers.<\/p>\n

  This next pug, a fairly large one, is boldly marked, and, one would hope, easy to identify.  Alas, it is one of two look-alikes, E. ravocostaliata <\/em>and E. nevadata<\/em>.  The mid-costal dark patch is supposed to be triangular (like this one) on nevadata <\/em>and rectangular on ravocostaliata<\/em> – but who knows?  I haven’t reared either, writes Jeremy Tatum, but the caterpillar of ravocostaliata<\/em> has been found on Salix<\/em>.<\/p>\n

Pronunciation:   RAY-vo costallyAHta.<\/p>\n

   The pugs are not the only small geometrids that are hard to identifiy.  The two waves Venusia obsoleta <\/em>and V. pearsalli<\/em> are a difficult pair.<\/p>\n
