Habitat
Stored products; associated with granary and warehouse environments where dried organic materials are stored.
Distribution
Recorded from Portugal, Nicaragua, Tanzania, Norfolk Island, Denmark, Norway, and Sweden. Distribution likely broader due to human-mediated transport with stored goods.
Life Cycle
Antennal growth occurs through addition of new segments to the at each moult, a pattern differing from other . The female possesses two ovaries with five polytrophic each. The male includes bipartite glandular seminal vesicles and a with a terminal adapted for gripping the female spermathecal papilla.
Ecological Role
Pest of stored products. No other ecological roles documented.
Human Relevance
Recognized as a pest of stored products, indicating economic significance in food storage and warehouse management. Human-mediated likely facilitates spread to new geographic regions.

Anatomical features
Lepinotus patruelis exhibits several distinctive anatomical traits: pigment (possibly melanin) deposited in ectodermal regions including the stomodaeal wall; serving as both food storage and digestion site; four with ends attached to the ; a single-chambered heart with two groups of pericardial nearby; two pairs of labial glands (basophile and acidophile) with ducts; and complex that are injected in liquid form and solidify within the spermatheca.
Phylogenetic relationships
Anatomical similarities in labial glands, and pericardial , and reproductive organs support the hypothesis that are closely allied to (sucking lice), as first suggested by Snodgrass (1905).
