macrodontia cervicornis Giant Longhorn from Bolivia

Hi Lauren,
This is a Giant Longhorn Beetle, Macrodontia cervicornis. We found information on Wikipedia that states: “Macrodontia cervicornis is the largest and best-known member of this genus of long-horned beetles, and this species is sometimes considered the second longest among all beetles, with known specimens exceeding 17 cm in length. A fair bit of this length, however, is due to the enormous jaws, from which it derives both of the names in its binomen; Macrodontia means ‘large tooth’, and cervicornis means ‘deer antler’. For that reason, it is generally excluded from consideration by purists who do not take the jaws, legs , or antennae of a beetle into account when determining length. This species is known from the rain forests of Colombia ,Peru ,Bolivia , the Guianas, and Brazil , but there are an additional seven described species in the genus, extending the overall range of the genus from Guatemala to Argentina .”

Hi Daniel,
Impressive images of that beetle. There’s evidence that these guys were once meals in the Amazonian rain forest; a desirable serving not only of protein and vitamins but of pleasing and energy-giving fats. While that still might be true, I have a feeling that these days someone finding a grub in the jungle would be likelier to raise it to adulthood and sell it as a specimen than eat it. Which is kind of sad, really. Best,
Dave
