Hi Line I am pretty sure they are book lice, Psocoptera, most likely Liposcelis species (Liposcelidae). Unfortunately Liposcelis species are very common in human habitats, some of them became significant stored product pest.
There is a pretty informative article on Wikipedia and down at the bottom there is a list of excellent references. http://en.wikipedia.org/wiki/Museum_integrated_pest_management Andras Szito | Taxonomist/Curator Plant Biosecurity | Entomology Department of Agriculture and Food, Western Australia 3 Baron-Hay Court, South Perth WA 6151 Locked Bag 4 | Bentley Delivery Centre WA 6983 t +61 (0)8 9368 3571 | f +61 (0)8 9368 2958 e andras.sz...@agric.wa.gov.au<mailto:andras.sz...@agric.wa.gov.au> w www.agric.wa.gov.au<http://www.agric.wa.gov.au> From: Line Hallbjørnsson [mailto:l...@mfs.dk] Sent: Tuesday, 12 May 2015 5:45 PM To: pestlist@museumpests.net Subject: [pestlist] identification Dear all We just found these tiny little pest in our tea that is sold in the shop and served in the café at our museum. Both are situated in the museum with easy access to exhibitions. Can anybody help in identifying them, and are they a threat to the museum objects? They seem as if they live in the wooden containers that the tea arrive and are sold in, as seen in the picture. They are approx. 1mm long and brownish/grey in colour. Would really appreciate any help!
