Red & Yellow Ornate Checkered on Same Plant - Trichodes ornatus

Red & Yellow Ornate Checkered on Same Plant - Trichodes ornatus
Emigrant Canyon, Death Valley National Park, Inyo County, California, USA
April 10, 2009
Above is the yellow form of Trichodes ornatus on flower petal of a beavertail cactus (Opuntia basilaris). The red form was also present on the same plant (see 2nd image in this series). So clearly the two color forms are not geographically isolated. And Margarethe's post here shows they seem to get along pretty well :-)

Interesting Observation: Before posting this (on 6/22/11), BugGuide had posts of 51 different individuals of the yellow form of T. ornatus and only 6 of the red form. That's an 8.5 to 1 ratio! I wonder if that faithfully represents the actual ratio of yellow-to-red T. ornatus out there in wild populations? (I kinda doubt it...at least in my personal experience, seems I see red ones more often than yellow ones!)

Red & Yellow Ornate Checkered on Same Plant - Trichodes ornatus Red & Yellow Ornate Checkered on Same Plant - Trichodes ornatus

In the South Bay area I see only the yellow form...
I’ve photo’d dozens in the past ten years in several different plants (yarrow, Clarkia spp, Calichortus spp, wild morning-glory); have yet to find the red form here.
