The Blind Small-eared Shrew (Cryptotis niausa) is a species in the genus Cryptotis. It is currently classified as Data Deficient on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Common Drill

<em>Dichrorampha petiverella</em>, the common drill, is a moth in the family Tortricidae. This species is distributed across Belgium, Denmark, Norway, Sweden, and the United States, typically inhabiting terrestrial and freshwater environments including meadows, grasslands, and woodland margins. The common drill is a small, cryptically patterned tortricid moth, often with brownish or grayish wing markings that provide camouflage against bark and plant surfaces. Adults are generally nocturnal and are often attracted to light. Larvae of <em>Dichrorampha petiverella</em> are typically root-boring, feeding internally within the roots of herbaceous plants, particularly members of the family Asteraceae. This feeding habit can occasionally cause economic damage to cultivated plants but is generally considered minor in natural ecosystems. The species is assessed as Least Concern, reflecting stable populations across its range. Biological traits of this moth beyond those documented here remain relatively poorly detailed in the broader scientific literature.
