Subject: Ecuadorian Beetle
January 7, 2016 8:29 pm
I photographed this beetle at Cabanas San Isidro, Ecuador, which is on the east slope of the Andes at about 6000′ elevation. Is it in the family Carabidae? Or, something else? Thanks for any help you can provide.

Though it does resemble a Ground Beetle in the family Carabidae or a Stag Beetle in the family Lucanidae, we believe we have correctly identified your individual as a Pole Borer in the genus Neandra from the Longhorned Borer Beetle family Cerambycidae based on this nearly identical image from BugGuide. Though you found this critter in South America, we turned to BugGuide, the premier insect identification site in North America, to research some information on Carabidae, and we found the image in the section on the BugGuide Carabidae site that is “Other beetles superficially resembling carabids.” According to BugGuide, the Pole Borer is found in: “moist decaying wood; larvae bore in trees and structural wood (poles, crossties, etc.) in contact with moist ground; adults may emerge, mate, and lay eggs in the same cavity they occupied as a larva.” Finally, Project Noah reports the Pole Borer from Ecuador.
