black carpet beetle
Refers specifically to the species Attagenus unicolor japonicus, a common household pest in Japan. The name is usually written in katakana.
The larvae of the black carpet beetle damage clothing.
I found a black carpet beetle in the closet.
カツオブシムシ is a broader term for dermestid beetles (family Dermestidae), while ヒメカツオブシムシ is a specific species within that group.
Katakana spelling is standard for this insect name; usually written in kana.
Kanji spelling is rare and mainly found in taxonomic or older texts; the katakana form is strongly preferred.
The name combines 姫 (hime, 'princess' or 'small') with 鰹節虫 (katsuobushi-mushi, 'bonito-flake insect'), referring to a small beetle often found in dried bonito flakes. The exact derivation is uncertain, but the name likely describes its small size and habitat.
