Isodontia apicalis
grass-carrier wasp
Isodontia apicalis is a solitary thread-waisted wasp in the family Sphecidae, known as a 'grass-carrier' for its distinctive nesting behavior. The species occurs in North and Central America. Like other members of its genus, females construct nests using dry grass to partition cells and plug entrances.
Parancistrocerus rectangulis
Parancistrocerus rectangulis is a small solitary mason wasp in the subfamily Eumeninae. Like other members of its genus, it nests in pre-existing cavities such as hollow twigs or beetle borings, provisioning cells with paralyzed caterpillars as food for its larvae. The species was described by Viereck in 1908. Specific natural history details for this species remain poorly documented in published literature, though genus-level traits suggest typical eumenine biology.
Parancistrocerus toltecus
Parancistrocerus toltecus is a small mason wasp in the subfamily Eumeninae. As a member of this genus, it is a solitary cavity-nesting wasp that provisions its nests with paralyzed caterpillars for its larval offspring. The species was described by de Saussure in 1857. Like other Parancistrocerus species, it likely utilizes pre-existing hollow twigs or beetle borings in dead wood for nest construction. Very little specific information has been published about the natural history of this particular species.
