What's an ambrosia beetle? How do you go about finding one? Learn all of this and more as we interview Dr. Rachel Osborn of the A.J. Cook Arthropod Research Collection at Michigan State University. She'll take us on an adventure with a tribe of beetles about the size of a grain of rice, and reveal a newly-discovered clue to their evolutionary history. Dr. Rachel Osborn’s paper “New Xyleborine (Coleoptera: Curculionidae: Scolytinae) Genus With an Afrotropical-Neotropical Distribution” is in Volume 6, Issue 4 of Insect Systematics and Diversity.  It can be found here: https://doi.org/10.1093/isd/ixac016 New Species: Xenoxylebora pilosa, Xenoxylebora addenda, Xenoxylebora calculosa, Xenoxylebora hystricosa, Xenoxylebora serrata, and Xenoxylebora sulcata (Osborn, Smith & Cognato).
