Guam Insects

It has been stated that a rhinoceros beetle can lift 850 times its own weight.  In a lab experiment, Dr. Roger Kram, UC Berkely, showed that Oryctes rhinoceros, the species found on Guam, can lift 100 times its own weight.  See the video.

The Insects of Micronesia series is a primary reference for entomologists working in Micronesia and elsewhere in the Pacific.  Volumes originally published by the Bishop Museum are now available as PDF documents at the following at http://hbs.bishopmuseum.org/pubs-online/iom.html.  Kudos to the Museum for sharing this library with the Pacific entomological community.  Most of these valuable documents are out print and are very hard to find.

Up to 1984 [vol. 9(2)], Insects of Micronesia issues were published at the Bishop Museum. After that, issues were published simultaneously in Micronesica with pagination for that journal but also given Insects of Miconesia pagination.

Bob Bourgeois brought in several small scarab larvae feeding in a dead coconut log at Ritidian Point (coordinates needed).  These do not look like Oryctes rhinoceros.  They crawl on their front and their foreheads are smooth and light yellow (photo needed).  Live specimens kepts for rearing.
