These are larval exuviae (cast skins) of Dermestidae, very probably of the genus Trogoderma. The main synanthropic genera of Dermestidae having larvae with arrow-like hairs (hastisetae) are Trogoderma and Anthrenus. Larvae of Anthrenus don't have, however, a 'tail' of long hairs at the posterior end of the abdomen; tail which is present, instead, in the exuviae of these photos. Regards,
