On June 5, 2014, a team of nine entomologists returned from a 12-day termite journey to Peru. The team drove from Lima, over the Andes (4, 818 m. elev.), to far western Amazonia, and back. The expedition yielded about 100 species including a number of new termite taxa and many new country records. This trip marks 25 years of termite diversity surveys beginning with a 1990 expedition to the Turks and Caicos Islands. To date, the UF collection contains over 40,000 colony samples in ethanol representing 1,788 collector-days of field work (not including contributions from African, Asian, and Australian colleagues, and the pest control community). There are about 140 undescribed species and over 1,000 described species in the collection. The collection is the largest contemporary (post-WWII) collection of termites in the world and has been the source for about 60 refereed journal articles.

Dr. Marc Branham was interviewed by Ira Flatow on National Public Radio’s Science Friday radio show this 4th of July. Dr. Branham talked about firefly biology and evolution, and suggested activities for how adults and children can communicate with fireflies in their own backyards.
A brief video about fireflies, composed of excerpts from the upcoming documentary Brilliant Darkness, is featured on the NPR Science Friday website. This video included interviews from Dr. James Lloyd and Dr. Marc Branham.
Last month, Dr. Marc Branham was interviewed and some of his firefly research filmed for a National Geographic/NOVA special on bioluminescence. Filming on this project will continue into 2015 with an anticipated release date of 2016. Dr. Branham’s firefly research is featured on the UF Office of Research homepage.
Dr. Billy Crow and his graduate student Tina Gu, along with colleague Dr. Bruce Martin and his graduate student Brad Shaver from Clemson University, were invited to spend a week in Switzerland as guests of Syngenta Lawn and Garden. They each made presentations of their research with Syngenta chemistries and learned a great deal about the pesticide business.

Ms. Nathalia Gomez joined the laboratory of Dr. James P. Cuda on 8 June. Ms. Gomez, a gifted high school student who hails from St. Lucie Co., is participating in the 56th Annual Student Science Summer Training Program, which is sponsored by the UF Center for Precollegiate Education and Training. Nathalia will be assisting with host range studies on the Brazilian peppertree stem boring weevil, Apocnemidophorus pipitzi.
Ms. Shannon Moore, an undergraduate student majoring in Wildlife Ecology and Conservation at UF, joined the laboratory of Dr. James P. Cuda on 30 June. Ms. Moore was awarded an FAES Summer Internship to study the impact of the stem boring weevil A. piptizi on Brazilian peppertree.
Need to name that bug? A host of experts are available to help Floridians identify any insect or related arthropod. If a mystery creature has six or more legs, the UF Insect ID Lab is the place to call.
ABOVE: Occasionally, the UF Insect ID Lab recieves samples of this minute beetle from inside a house. The samples may include only larvae, only adults, or both. At first glance, the adult resembles a rove beetle, but it actually is the sole member of the family Micromalthidae. It is Micromalthus debilis, also called the telephone-pole beetle. The larvae are wood borers and can be found in moist, decaying oak logs. Indoors, they can develop in wood that stays moist because of a water leak or condensation. They are a nuisance pest indoors because dozens or hundreds of them may be found, but the bigger issue for homeowners is finding and correcting the problem that is causing the moist wood.
Lyle Buss is the Insect ID Lab manager.

The Bark & Ambrosia Beetle Academy
Just a few weeks ago, the Entomology & Nematology building saw a large group of people scurrying around the hallways like a little bark beetle colony in their subcortical gallery. The Department hosted the Bark & Ambrosia Beetle Academy. From May 8 to May 13, thirty participants from around the world (Australia, Germany, South Africa, Puerto Rico, Norway, Guam, Italy, and many US states from Connecticut to California) convened here to learn, discuss, and have fun collecting bark and ambrosia beetles. We also hosted several IFAS Extension county faculty.
The Academy was split into three modules, covering everything from beetle management, to hands-on training in identification, to techniques for field collection (including an exciting night light-trapping event at the new fancy SFRC Learning Center in the Austin Cary Forest), and specialized topics ranging from molecular identification to bark beetle acoustics.
The team was extraordinary – our ENY M.S. student Sedonia Steininger essentially ran the show, and several other people from the Hulcr lab were always at hand (Caroline Storer, Craig Bateman, Andrew Johnson and Adam Black). The main attraction was probably the array of heavyweights from the scolytine beetle research community, including the world’s most prominent systematists, ecologists and management researchers.
We would like to thank the Entomology and Nematology Department for the facilities that were made available, and to the many individuals who supported us during the event, particularly Nick Hostettler, Elena Alyanaya, and Dr. Andrea Lucky whose lab turned into a temporary bark beetle junk storage. We are also grateful to Kate Okins from the Department of Plant Inspection for providing specimens and identification expertise and Jeff Eickwort from the Florida Forest Service for helping us to locate field sites. The School of Forest Resources and Conservation graciously provided vans for transport and the beautiful Learning Center. This was a prime example of a symbiosis between the two Departments.
Dr. Marc Branham gave an invited presentation in the Institute of Learning in Retirement seminar series titled Bioluminescence and Courtship Communication in Fireflies.
Ms. Nathalia Gomez presented an overview of her summer research project on the Brazilian peppertree weevil A. pipitzi as part of the SSTP midterm oral presentation program held on campus at the Health Professions, Nursing and Pharmacy Complex, 27 June.

From the Outreach Coordinator
The live critters are always a hit with children and adults alike. The critters are available for you to check out should you be leading an outreach event. We have doubles of our most popular critters, as well as various native insect species depending on the time of year. We have large wood and Plexiglas cages for viewing our native orb weaving spiders. There is one travel cage and one larger static cage. Please be sure to contact us and review the protocol on transporting and handling the critters if you are not already familiar with it. If you lead an outreach, be sure to fill out a documentation form so your event can be included in the newsletter and we can log all outreach events.
