Habitat
Agricultural fields and areas where plants occur. have been observed on a variety of plants, while larvae develop within stems.
Distribution
Central America and North America. Specific regional records include Manitoba, Canada.
Diet
Larvae feed internally within stems of plants. Documented hosts include red clover (Trifolium pratense), canola, and soybeans (Glycine max).
Host Associations
- Trifolium pratense - larval development in stemsprimary implied by
- canola - new record; larval stem boringdocumented in Florida Entomologist 2007
- Glycine max (soybeans) - new recorddocumented in Florida Entomologist 2010
Life Cycle
Larval development occurs within plant stems. Specific details of , pupal, and timing are not documented in available sources.
Behavior
Stem boring : larvae tunnel inside plant stems, potentially weakening plants. are found on vegetation but specific adult behaviors are not well documented.
Human Relevance
Documented as a pest of agricultural crops including canola and soybeans. The ' expansion to multiple crop suggests potential economic significance in agricultural systems, though specific damage assessments are not detailed in available sources.
