Parasitic activity or over heating of the pupa likely killed this male photographed March 1, 2006. Canon 20D 100mm lens, ISO 200, F20, 1/250, Flash + 1 2/3 Specimen Photos ©Todd Stout Host Plant Photo and information 1. Yucca angustissima , Washington County, Utah. The larvae initiallly feed on leaves and then, when they get older, they burrow into the roots of the plant; drilling out a tunnel right in the root of the plant. (This of course kills the plant). The larvae of Megathymus yuccae coloradensis make a conspicuous nest in the middle of the plant that lets you know a larva was there. The nest is made out of its dung pellets. - ©Todd Stout Back to Top |
