Pathways of introduction

Transport - Contaminant: Seed contaminant.

The species was found on fields, thus indicating its arrival with contaminated seed.

This casual alien has not been known prior to the period of its first record and had hardly had a chance for longer survival in the agricultural habitats.

Invasion status
