Iron Cross Blister Beetle - Tegrodera latecincta

Iron Cross Blister Beetle - Tegrodera latecincta
Manzanar Japanese Relocation Camp, Inyo County, California, USA
June 25, 2006
Size: 1 - 2 in.
While hiking in the Sierras, my friend and I paid a visit to the Manzanar Japanese Relocation Camp (http://www.nps.gov/manz/). While checking out the memorial, I noticed these beetles all over the place. They were eating small plants that were growing through the gravel... . They are pretty quick for their size and do not like cameras in their little beetle faces (which kind of look like large ant heads).. they turn around immediately, everytime.

This one is Eating.

For more information on the poisonous chemical compound secreted by the Blister Beetle, I urge all to visit the Wikipedia site for Cantharidin.

Something interesting: "Diluted, it can be used to remove warts and tattoos. In addition, it can be used to treat the small papules of Molluscum contagiosum. However, when ingested 10 mg is usually a fatal dose."

Looks like it's on it primary host plant here
...which are species of the genus Eriastrum. It's a bit blurry, but I think I can make out the characteristic spiny & densely short-woolly flowering heads characteristic of members of that genus (though they're not conspicuously flowering in the plant here).

Location of these Blister Beetles on Google Maps
I can't believe it's been so long since I posted these photos, 2006?! Wow. Well, I wanted to update the post with a link to Google Maps and a location marker for the *exact* location of these beetles. I urge those of you who are interested and in the area, make a quick stop and see if you can spot them. Besides the beetles, Manzanar is a pretty amazing historical stop along the 395.
