Pseudohylesinus tsugae
Pseudohylesinus tsugae is a crenulate bark beetle in the family Curculionidae, native to western North America. It has a univoltine life cycle with two broods and four larval instars, overwintering as a fourth-instar larva. The species is closely associated with western hemlock (Tsuga heterophylla), where adult females feed on the inner bark of living trees before breeding in fresh stumps. It is distinguished from the sympatric P. grandis by its preference for stumps over slash as breeding substrate.
Scaphinotus cordatus
Heart-shaped Thorax Snail-eating Beetle
Scaphinotus cordatus is a species of ground beetle in the family Carabidae, commonly known as the Heart-shaped Thorax Snail-eating Beetle. It is found in North America, specifically in California, where it inhabits coastal mixed forests. Adults are brachypterous (short-winged), a trait common in the genus Scaphinotus. The species belongs to the tribe Cychrini, a group of large ground beetles often referred to as "snail hunters" due to their specialized diet.
Zootermopsis nevadensis nuttingi
Zootermopsis nevadensis nuttingi is a subspecies of dampwood termite in the family Archotermopsidae, described by Haverty & Thorne in 1989. It inhabits coastal forests of the western United States where it contributes to wood decomposition through specialized hindgut symbionts. The subspecies is distinguished from other Z. nevadensis populations by morphological and geographic characteristics. Like other dampwood termites, it requires moist wood substrates and lacks the specialized adaptations for arid environments seen in drywood termites.
