Anthrenus zahradniki

Anthrenus zahradniki was first described by Jiří Háva in 2003 in the journal Klapalekiana, published by the Czech Entomological Society. It is classified within the subgenus Nathrenus Casey, 1900, and placed in the "verbasci" species group alongside its closest known relative, Anthrenus biskrensis Reitter, 1887. Háva's original description compares the two species in detail and provides diagnostic illustrations. The specific epithet zahradniki is a Latinised genitive patronym honouring Petr Zahradník, a Czech entomologist at the Forestry and Game Management Research Institute in Prague who specialises in the taxonomy of Ptinidae and Bostrichidae. Fauna Europaea and some other databases have listed the species under the subgenus Florilinus rather than Nathrenus. However, the original description explicitly places it in Nathrenus, and this classification is followed by Háva's regularly updated World Dermestidae Catalogue. == Description ==

Like other members of the genus Anthrenus, A. zahradniki is a small, rounded beetle, with the genus ranging from 1.8 to 4 mm in body length. The dorsal surface is covered in fine, petal-shaped scales of varying colours, typically white, brown, yellowish, and dark, that form species-specific patterns on the elytra. These scales wear off with age, revealing the shining black cuticle beneath. As a member of the subgenus Nathrenus, the species is characterised by 11-segmented antennae terminating in a club (larger in males than females), and by lacking an indentation on the inner margin of the eye, a feature that distinguishes Nathrenus from the nominate subgenus Anthrenus. Body scales in Nathrenus are generally more than twice as long as wide. The original description distinguishes A. zahradniki from the very similar A. biskrensis through differences in scale patterning and male genitalic structure. == Distribution ==

Anthrenus zahradniki has an eastern Mediterranean distribution. It was originally described from Turkey (the type locality). Subsequent records have extended its known range to the Greek islands of Chios and Rhodes, Cyprus, and Lebanon. Háva and Németh published the first record from Lebanon in 2016. The distribution of A. zahradniki is complementary to that of its closest relative, A. biskrensis, which occurs across the western and central Mediterranean (Italy, Malta, Spain, and North Africa). As of 2026, no digitised occurrence records for the species exist in the Global Biodiversity Information Facility (GBIF); the species is known primarily from museum specimens documented in taxonomic literature. == Ecology ==

No species-specific ecological studies of A. zahradniki have been published. Its biology is presumed to follow the general pattern well established for the genus Anthrenus. Adults Adult Anthrenus beetles are pollen and nectar feeders, commonly found on flowers of Apiaceae and Asteraceae. They are active fliers during spring and summer and function as minor pollinators of the plants they visit. Adults live for approximately two weeks. Larvae Larvae are the destructive life stage, feeding on dry animal-derived materials rich in keratin, including fur, feathers, wool, shed skin, and dried insect remains. In natural habitats, larvae are typically found in bird nests, bat roosts, and tree hollows where such debris accumulates. They are covered in long defensive hairs known as hastisetae, a characteristic shared across the genus. Several Anthrenus species are significant pests of museum collections and textiles, though there is no evidence that A. zahradniki has pest status. Life cycle Anthrenus beetles undergo complete metamorphosis. Females lay 35 to 100 eggs, which hatch in one to three weeks. The full life cycle takes 4 to 12 months depending on temperature and food availability. The majority of Anthrenus species are associated with semiarid regions of Europe, Asia, and Africa. == Conservation status ==

Anthrenus zahradniki has not been assessed by the IUCN Red List or any other conservation body. == References ==
