Andricus lustrans
Beutenmuller, 1913
Andricus lustrans is a of cynipid gall wasp described by Beutenmuller in 1913. Like other members of the Andricus, this species induces characteristic galls on oak trees (Quercus spp.), with gall formation triggered by chemical secretions from the developing larva that manipulate plant . The specific gall and associations distinguish it from related species. emerge from galls to reproduce and initiate new gall .

Identification
Identification relies primarily on the distinctive gall produced on oak tissues, as are minute and morphologically similar to other Andricus . The specific gall structure induced by A. lustrans differs from such as A. dimorphus (clustered midrib galls on Quercus muhlenbergii) and A. pattoni (abaxial leaf galls on Quercus stellata). Precise identification requires examination of gall position, shape, and host species association.

Habitat
Found in supporting its oak , including dry-mesic upland deciduous forests and oak-dominated woodlands. Occurs in areas where suitable Quercus host trees are present and established.
Distribution
Documented from North America; specific range details limited in available sources. GBIF records indicate presence in the United States. Associated with eastern and central oak forest regions where occur.
Seasonality
and gall initiation occurs during the growing season when oak leaves and twigs are actively developing. Specific not documented in available sources.
Host Associations
- Quercus - gall Specific not confirmed in available sources; belongs to containing numerous Andricus host species
Life Cycle
Follows the typical cynipid pattern: female deposits in oak tissue using ovipositor; larval secretions induce gall formation; larva develops within gall, feeding on specialized plant tissue; occurs within gall; emerges by chewing exit hole. Development completes while gall attached to plant. Specific details for A. lustrans not documented.
Ecological Role
As a gall inducer, creates microhabitats that may be utilized by other organisms (, ). Contributes to biodiversity of oak-associated . Galls represent a form of plant-insect interaction demonstrating manipulation.
Human Relevance
No direct economic or medical significance documented. Like other cynipid , contributes to oak dynamics and serves as subject for studies of plant-insect interactions and gall .
