Pleocoma badia
rain beetle
Pleocoma badia is a species of rain beetle in the family Pleocomidae, first described by Fall in 1917. It is found in North America and includes two recognized subspecies: P. b. badia and P. b. hirsuta. Rain beetles are notable for their emergence during rainfall events and fossorial (burrowing) lifestyle.
Pleocoma badia hirsuta
Pleocoma badia hirsuta is a subspecies of rain beetle in the family Pleocomidae, described by Davis in 1934. Like other Pleocomidae, adults are active during autumn rains and exhibit strong sexual dimorphism with flightless females. The subspecific epithet 'hirsuta' suggests increased hairiness relative to the nominate subspecies. It is one of several subspecies within the P. badia species complex found in western North America.
Pleocoma behrensii
rain beetle
Pleocoma behrensii is a species of rain beetle endemic to the Pacific Coast of North America. Rain beetles in this genus are known for their flightless females and their emergence during the first heavy autumn rains. The species belongs to a relict family with limited distribution and specialized ecological associations.
Pleocoma bicolor
rain beetle
Pleocoma bicolor is a species of rain beetle in the family Pleocomidae, described by Linsley in 1935. Rain beetles in this genus are known for emerging in response to rainfall events. The species is endemic to California.
Pleocoma blaisdelli
rain beetle
Pleocoma blaisdelli is a rain beetle in the family Pleocomidae, described by Linsley in 1938. It is one of approximately 30 species in the genus Pleocoma, all endemic to western North America. Rain beetles are named for their habit of emerging during autumn or winter rains to mate. The species is recorded from California. Like other Pleocoma, adults are sexually dimorphic and do not feed.
Pleocoma crinita
rain beetle
Pleocoma crinita is a species of rain beetle described by Linsley in 1938. It is one of approximately 30 species in the genus Pleocoma, a group of large, fossorial scarab beetles endemic to western North America. The species is known from Washington State and shares the family-wide trait of adult emergence triggered by rainfall.
Pleocoma dubitabilis
rain beetle
Pleocoma dubitabilis is a rain beetle species in the family Pleocomidae. It is known from North America and comprises two recognized subspecies: P. d. dubitabilis and P. d. leachi. The nominate subspecies has been documented as a pest of commercially grown Christmas trees, specifically feeding on Abies species.
Pleocoma dubitabilis leachi
Pleocoma dubitabilis leachi is a subspecies of rain beetle in the family Pleocomidae, described by Linsley in 1938. It belongs to a genus of scarab beetles endemic to western North America, commonly known for their autumn emergence following rainfall. Members of this genus are characterized by strong sexual dimorphism and fossorial habits. The subspecies designation indicates geographic variation within P. dubitabilis.
Pleocoma fimbriata
Fimbriate Rain Beetle
Pleocoma fimbriata is a species of rain beetle in the family Pleocomidae, known from California. Rain beetles are characterized by their flightless females and autumn-emerging adults that are often associated with rainfall events. The species was described by LeConte in 1856.
Pleocoma hirticollis
rain beetle
Pleocoma hirticollis is a species of rain beetle in the family Pleocomidae, a group of scarab beetles endemic to western North America. The species is active during autumn and winter rains, emerging only when soil is saturated. Three subspecies are recognized: P. h. hirticollis, P. h. reflexa, and P. h. vandykei. Like other Pleocomidae, adults are sexually dimorphic and do not feed.
Pleocoma hirticollis vandykei
Pleocoma hirticollis vandykei is a subspecies of rain beetle in the family Pleocomidae. It is one of several subspecies within the species P. hirticollis, which belongs to a genus of scarab beetles endemic to western North America. Members of Pleocoma are known for their fossorial habits and adult emergence during autumn rains. This subspecies was described by Linsley in 1938 and is currently accepted as valid.
Pleocoma hovorei
Pleocoma hovorei is a rain beetle species described in 2007. It belongs to the family Pleocomidae, a small group of scarab beetles known for their emergence during autumn rains. The species occurs in California, USA.
Pleocoma linsleyi
rain beetle
Pleocoma linsleyi is a species of rain beetle described by Hovore in 1971. The species was named in honor of American entomologist Earle Gorton Linsley. It belongs to the family Pleocomidae, a group of scarab beetles known for their autumn emergence patterns and association with rainfall.
Pleocoma marquai
rain beetle
Pleocoma marquai is a species of rain beetle described by Hovore in 1972. It belongs to the family Pleocomidae, a small group of scarab beetles known for their emergence during autumn rains. The species is known from California and is one of approximately 30 species in the genus Pleocoma.
Pleocoma octopagina
rain beetle
Pleocoma octopagina is a species of rain beetle described by Robertson in 1970. It belongs to the family Pleocomidae, a small group of scarabaeoid beetles known for their autumn emergence following rainfall. The species occurs in California on the lower West Coast of North America.
Pleocoma oregonensis
Oregon rain beetle
Pleocoma oregonensis is a rain beetle in the family Pleocomidae, endemic to the Pacific Northwest region of North America. As with other members of this family, it exhibits autumnal emergence patterns correlated with rainfall events. The species was described by Leach in 1933 and is one of approximately 30 described species in the genus Pleocoma.
Pleocoma puncticollis
Black Rain Beetle
Pleocoma puncticollis, commonly known as the black rain beetle, is a species of rain beetle in the family Pleocomidae. It is endemic to California. Adults are known to emerge and fly during rainy conditions, a trait characteristic of the genus.
Pleocoma rubiginosa
Sierran Rain Beetle
Pleocoma rubiginosa is a species of rain beetle described by Hovore in 1972. The species is endemic to North America and comprises two recognized subspecies: P. r. rubiginosa and P. r. transsierrae. As a member of the family Pleocomidae, it shares the group's common name reflecting adult emergence patterns associated with rainfall.
Pleocoma simi
Pleocoma simi is a rain beetle in the family Pleocomidae, described by Davis in 1934. The species is known from Oregon in the western United States. As with other Pleocoma species, adults are active during autumn rains and males fly to locate flightless females. Larval stages remain underground, feeding on roots.
Pleocoma staff
rain beetle
