Large Coreid Bug, the Western Leaf-footed Bug, was found on a bush half way to the top of Angel's Landing, in a shaded forested area. Note the prominent orange spine on the head between the antennae. This one has orange abdominal bands and a pale orange, but distinct wavy line across the elytra. The antennae are unicolor. About 2.5 cm long. Family Coreidae.

Surprisingly, there are now 61 species of Leptoglossus! L. occidentalis is probably the most often seen and now also occurs in Europe as an invasive species. This species, L. clypealis is quite distinct from L. occidentalis, with more pronounced markings and a much longer spine on the front of the head (among other differences). The following revision of the species of Leptoglossus by Brailovsky in 2014 gives a key and dorsal drawings of all species. http://www.ib.unam.mx/m/documentos_de_ac....
