noun
erythaeid mite
A type of small red mite of the superfamily Erythraeoidea, often seen on the ground or on plants. Not harmful to humans.
春になると、庭でタカラダニをよく見かける。
In spring, I often see erythaeid mites in the garden.
タカラダニは赤くて小さいので、ダニと間違えられることがある。
Because erythaeid mites are red and tiny, they are sometimes mistaken for ticks.
ダニ is the general term for ticks and mites, while タカラダニ refers specifically to the erythaeid mite.
The name タカラダニ literally means 'treasure mite', but the exact origin is uncertain. It may refer to the bright red color resembling a treasure, or derive from an old name.
