LOCATION: Krimpen aan den IJssel, garden


The Common mallow (Malva sylvestris) plants in the garden are permanently inhabited by this ±3mm large weevil Aspidapion radiolus [1,2]. Their numbers can reach several tens to hundred specimen which has a detrimental effect on the host plant that will be completely covered in circular feeding scars on its stem, leafstalks, and leafs over time.
This couple is taking care of the next generation that will appear in August and September [2]. Common mallow is one of the species host plants. Their larvae develop inside the hollow stems and leafstalks [2].
