Guides

  • Friseria

    mesquite web worm (for F. cockerelli)

    Friseria is a genus of small moths in the family Gelechiidae, established by Busck in 1939. The genus contains at least nine described species distributed in North America. One species, Friseria cockerelli, is known as the mesquite web worm and has been studied for its larval habit of constructing silken webs on host plants. Most species remain poorly documented beyond taxonomic descriptions.

  • Friseria acaciella

    Friseria acaciella is a small gelechiid moth with a wingspan of approximately 13 mm. The species is distinguished by its dark purple forewings with a distinctive yellowish-white quadrangular spot and contrasting lighter apex. It occurs in Mexico and the southern United States, with larvae that feed specifically on Acacia farnesiana.

  • Friseria cockerelli

    mesquite webworm moth, mesquite webworm

    Friseria cockerelli is a small moth in the family Gelechiidae, commonly known as the mesquite webworm moth. Its larvae are web-forming caterpillars that feed on mesquite (Prosopis spp.) and construct silk webs on host plants. The species occurs in Mexico and the southern United States, with adults active primarily from April to September.

  • Friseria nona

    Friseria nona is a small gelechiid moth described by Hodges in 1966. It is known from Arizona in southwestern North America. The species is morphologically similar to Friseria repentina but distinguished by buff coloration replacing the orange tones found in that species. Knowledge of this species is limited to original description and scattered records.

  • Gelechia

    Gelechia is a genus of small moths in the family Gelechiidae, first described by Hübner in 1825. The type species is Gelechia rhombella. Species in this genus are associated with various host plants including cotton (Gossypium), juniper (Juniperus), and Palo Verde trees (Parkinsonia).

    Gnorimoschema gallaesolidaginis is a small moth in the family Gelechiidae that induces distinctive elliptical galls on goldenrod (Solidago) stems. The species exhibits host-associated genetic differentiation, with populations on different Solidago species showing significant genetic divergence even when geographically proximate. Research has demonstrated that the galls formed by this moth accumulate soil contaminants at higher concentrations than surrounding plant tissues, making them potentially useful as environmental pollution detectors. The moth is widely distributed across North America and is one of several gall-forming insects associated with goldenrod.

  • Gnorimoschema nr-septentrionella-two

    Gnorimoschema nr-septentrionella-two is a species of gelechiid moth in the genus Gnorimoschema. The "nr" designation indicates this is a near-reference specimen that closely resembles but may not be definitively identified as Gnorimoschema septentrionella. The "two" suffix suggests it represents a second distinct morphotype or genetic cluster within this near-septentrionella group. Species in this genus are typically small moths associated with herbaceous host plants, often forming galls or feeding internally in stems or roots.

Its specific epithet 'triocellella' directly references the three eye-like wing markings that serve as key identification features.

  • Gnorimoschemini

    Gnorimoschemini is a tribe of small moths within the subfamily Gelechiinae (family Gelechiidae). Members are generally small, narrow-winged moths with drab coloration. The tribe includes species with diverse larval habits, including gall inquilines that develop within pre-existing plant galls rather than inducing their own.

As with many gelechiid moths, detailed life history information remains limited.

  • Hypatima sp-two

    Hypatima sp-two is an undescribed or provisionally designated species within the genus Hypatima, a diverse group of small moths in the family Gelechiidae. Species in this genus are generally characterized by narrow wings and often exhibit distinctive wing patterns useful for identification. The specific epithet "sp-two" indicates this taxon has not received a formal species description and is recognized by a working designation. As with many gelechiid moths, adults are likely nocturnal and larvae probably feed on plant material.

Adults are small, narrow-bodied moths approximately 8 mm long with brownish-gray coloration, light speckling, and large recurved antennae. Females deposit eggs at the base of knapweed flower heads, where larvae burrow inside to feed on developing seeds and florets. Larvae are small white grubs with dark heads that overwinter within seed heads and pupate the following spring. The species has been established across much of the western United States since its introduction in 1980.

Many species were originally described under other genera and later transferred to Mirificarma.

  • Mirificarma eburnella

    Mirificarma eburnella is a small gelechiid moth with a Palearctic distribution, now established in California as an introduced species. It is associated with leguminous host plants and has been studied as a potential biological control agent for invasive clovers. Adults are active in spring and early summer.
