Tryphoninae
Guides
Clivinematini
Clivinematini is a tribe of ichneumon wasps within the subfamily Tryphoninae. Members of this tribe are parasitoid wasps that target sawfly larvae (Hymenoptera: Symphyta) as hosts. The tribe is characterized by specific morphological features of the ovipositor and associated structures that distinguish it from related tryphonine tribes. Clivinematini represents a relatively small and specialized lineage within the diverse Ichneumonidae.
Idiogramma
Idiogramma is a genus of ichneumonid wasps and the sole extant genus in the tribe Idiogrammatini. The genus contains three described species: I. comstockii, I. elbakyanae, and I. euryops. It belongs to the subfamily Tryphoninae within the large parasitoid wasp family Ichneumonidae.
Netelia
Orange Ichneumon Wasp, Netelia Wasp
Netelia is a large genus of ichneumonid wasps in the subfamily Tryphoninae, comprising over 330 described species grouped into 12 subgenera. These medium to large wasps are typically orange to brownish-yellow in coloration with conspicuously long antennae and legs. Females possess a prominent ovipositor used to parasitize caterpillar hosts. Unlike many ichneumonids, Netelia females can deliver a painful sting when handled carelessly, using it to temporarily paralyze hosts before egg deposition. The genus is cosmopolitan in distribution and frequently attracted to artificial lights at night.
Polyblastus
Polyblastus is a genus of ichneumon wasps in the subfamily Tryphoninae. Females are koinobiont ectoparasitoids of sawfly larvae, carrying multiple small eggs externally on the ovipositor or abdomen. The genus has been documented in Europe and North America, with field observations in northern Germany and Colorado, USA. Some species have been observed with egg clusters attached to foliage, though the function of this behavior remains unclear.
Polyblastus fulvilinealis
Polyblastus fulvilinealis is a small ichneumon wasp in the subfamily Tryphoninae. It is a koinobiont ectoparasitoid of sawfly larvae, meaning the host continues development until the wasp larva completes its growth. Females have been observed carrying multiple eggs externally beneath the abdomen, a behavior whose precise function remains unclear. The species occurs in North America and has been documented in Colorado.
Polyblastus tibialis
A species of ichneumon wasp in the subfamily Tryphoninae. Documented from western Canada with records from Alberta. Belongs to a genus of koinobiont ectoparasitoids that attack sawfly larvae. The specific epithet 'tibialis' likely refers to a characteristic of the tibia.
Tryphon
Tryphon is a genus of ichneumon wasps in the family Ichneumonidae, subfamily Tryphoninae. Members of this genus are parasitoid wasps that develop as external parasites on sawfly larvae. Females possess a long, slender ovipositor used to deposit eggs on or near host larvae. The genus is part of the tribe Tryphonini, which is characterized by koinobiont development where the host continues to grow after parasitization.
Tryphon seminiger
Tryphon seminiger is a species of ichneumon wasp in the subfamily Tryphoninae. It is a koinobiont ectoparasitoid, meaning its larva feeds externally on a living host that continues to develop until the wasp completes its development. The species has been recorded in central Canada (Saskatchewan, Alberta) based on GBIF distribution data. As a member of Tryphoninae, it likely shares traits with related species in the genus, including nocturnal activity and attraction to artificial lights.
Tryphonini
Tryphonini is a tribe of koinobiont ichneumonid wasps within the subfamily Tryphoninae. Members are ectoparasitoids of sawfly larvae (Hymenoptera: Symphyta), with females possessing relatively large egg loads compared to idiobiont relatives. The genus Polyblastus is a well-documented member of this tribe. Females have been observed carrying egg clusters externally, possibly due to egg retention after unsuccessful oviposition attempts.
