Box 141874 Gainesville, FL 32614-1874 USA http://centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non-marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Ab- stracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Chief Editor: David Plotkin, e-mail: [email protected] Assistant Editor: Paul E.

Coprophagy and probable saprophagy are reported for larvae of two species of chrysaugine moths (Lepidoptera: Pyralidae). Larvae of Parachma ochracealis Walker are found in rotten pine wood and mulch in North-Central Florida. Larvae of Basacallis tarachodes (Dyar) inhabit feces of an unidentifi ed small mammal in a cave in Central Florida and seem to be troglophilic. These behaviors are compared to similar ones in Neotropical chrysaugines such as Humiphila Becker and Cryptoses Dyar. Saprophagy and coprophagy are predicted to be more general habits among Chrysauginae. Key Words. Neotropics, bark, sloth moth, troglophily. Introduction The fi rst records of larval behavior for two species of North American Chrysauginae (Lepidoptera: Pyralidae) are reported herein. As far as known, these are also the fi rst non-phytophagous records for any Nearctic Chrysauginae. Parachma ochracealis Walker (Fig. 1) is common and widely distributed in central and southern North America, from New Jersey and Missouri to Florida, Texas, and Arizona. The uncommon species Basacallis tarachodes (Dyar) (Fig. 5), originally described from Panama, is known from the Carolinas and Gulf Coast states to Texas and New Mexico (North American Moth Photographers Group 2016; M.A. Solis, pers. comm.). Cashatt (1984) revised these same two species. Parachma Walker currently comprises P. ochracealis in the Nearctic, nine Neotropical species, one on Réunion Island, and P. borregalis Dyar from southern Texas, which Cashatt (1984) synonymized with P. ochracealis but was reinstated by Solis et al. (1995). Cashatt proposed the separate monotypic genus, Basacallis Cashatt, for Parachma tarachodes Dyar. Although saprophagy and coprophagy were previously unknown for Nearctic chrysaugines, feeding habits like these, and even stranger ones, such as nest inquilinism and consuming spines of hemileucine larvae, are known for the Neotropical fauna (Jordan 1926; da Costa Lima 1950; Becker 1974; Waage and Montgomery 1976; Munroe and Solis 1998). 2 • INSECTA MUNDI 0553, May 2017 HAYDEN ET AL. Materials and Methods Specimens of adult moths were identifi ed by reference to Cashatt (1984) and comparison with specimens in the Florida State Collection of Arthropods (FSCA). Preserved larvae, pupae, and pinned adults were deposited in the FSCA (housed in the McGuire Center for Lepidoptera [MGCL], Florida Museum of Natural History, Gainesville, FL) and in the reference collection of Lyle Buss (University of Florida, Department of Entomology and Nematology). Samples of rodent feces and hair were deposited in the Florida Museum of Natural History Mammalogy Range. Genitalia of B. tarachodes were dissected following Robinson (1976) and slide-mounted in Euparal (MGCL slide nos. 3249 male, 3250 female). Some larvae of B. tarachodes were starved for a day to purge gut contents and were preserved in 100% ethanol at -20oC. Total DNA was extracted from each of three larvae of Basacallis tarachodes using the QIAGEN DNeasy Blood and Tissue kit. A 687-bp region of the mitochondrial COI gene was ampli- fi ed with a pair of primers, LepF1 and LepR1 (Hebert et al. 2004), using the following PCR conditions: 94oC for 1 min; 5 cycles of 94oC for 30 s, 45oC for 40 s, and 72oC for 1 min; 35 cycles of 94oC for 30 s, 51oC for 40 s, and 72oC for 1 min; and 72oC for 5 min. Each PCR contained 2 μl DNA, 1× PCR buffer, 2 mM MgCl2, 0.4 mM dNTPs, 0.2 μM of each primer, and 0.2 μl Platinum Taq DNA polymerase (Invitrogen) in a total volume of 20 μl. The PCR products were Sanger sequenced. The COI sequences obtained were edited using Geneious Pro 5.5.3 and deposited in GenBank (accession nos. KU530230–KU530232). To identify the mammal associated with B. tarachodes, hairs were isolated under a microscope from
