dear nancy, I would definitely consider it to be frass, in my opinion they are not insect eggs.
if the frass was found “at the end of a roll of tissue paper” it could be from Ctenolepisma longicaudatum. but it has too different shapes and colors to me. let’s see what the entomologists say… best regards V o l k e r H i n g s t Diplom-Restaurator Volker Hingst IPM-Koordinator --------------------------------------- LVR - Archivberatungs- und Fortbildungszentrum Technisches Zentrum / Papierrestaurierung Ehrenfriedstr.19 50259 Pulheim Tel.: 02234-9854-236 Fax: 0221-8284-2479 E-Mail: volker.hin...@lvr.de<mailto:volker.hin...@lvr.de> Internet: www.afz.lvr.de<http://www.afz.lvr.de/> Von: pestlist@googlegroups.com <pestlist@googlegroups.com> Im Auftrag von Jenner, Nancy@Parks Gesendet: Dienstag, 28.

All I have right now are these photos, and I'm trying to help her identify the source. Although she initially thought it was eggs, it seems more likely to be frass.... is there a good frass field guide? Also, what questions should I ask her to help narrow down the source? This is in California, in the Sierra foothills. Thanks very much for your assistance! --Nancy Nancy Jenner Curator II, Statewide Museum Collections Center California State Parks phone: 916-842-7834 -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
