Acanthosomatidae
Guides
Elasmostethus
Birch shieldbug
Elasmostethus is a genus of shield bugs in the family Acanthosomatidae, comprising approximately 15 described species distributed across the Holarctic region. The genus is notable for exhibiting asocial behavior—specifically, the absence of maternal care of eggs—contrasting with subsocial species found elsewhere in the family. Species within this genus show significant interspecific variation in life history traits including egg size, developmental periods, and female body size, though clutch size remains relatively consistent across species.
Elasmostethus cruciatus
red-cross shield bug, redcrossed stink bug, salmonberry bug
Elasmostethus cruciatus is a shield bug in the family Acanthosomatidae, commonly known as the red-cross shield bug or salmonberry bug. It is native to North America and recognized by the distinctive red cross pattern on its dorsal surface. The species is associated with salmonberry and other Rubus plants.
Elasmucha
Parent shieldbugs
Elasmucha is a genus of shield bugs in the family Acanthosomatidae, commonly known as parent shieldbugs. Species in this genus are notable for exhibiting subsocial behavior, specifically extended maternal care of eggs and early nymphal stages. Females guard egg masses and remain with offspring through early instars, actively defending against predators and parasitoids. The genus includes arboreal species associated with specific host trees, with documented seasonal host plant switching in some species.
Elasmucha lateralis
Edge-striped Shield Bug
Elasmucha lateralis is a shield bug in the family Acanthosomatidae, commonly known as the Edge-striped Shield Bug. It is native to North America, with distribution extending into Middle America. The species belongs to a genus noted for maternal care behaviors, though specific documentation of such behavior in E. lateralis is limited.
Ixapiini
Ixapiini is a small tribe of shield bugs within the family Acanthosomatidae, comprising the single genus Ixapion. These insects are characterized by their distinctive body shape and are primarily distributed in the Neotropical region. The group represents one of the more specialized lineages within the Acanthosomatidae, though detailed biological studies remain limited.
