Question

tree located in spacious domestic garden with multiple shoots in upper canopy effected leading to some crown thinning

Answer

Hi Kevin, the damage you see on the willow is caused by Stenacis triradiatus, also known as the triradial willow mite. This microscopic mite creates characteristic galls and dense, twisted clusters of shoots called witches’ brooms. It overwinters under bud scales and becomes active in spring, feeding on young shoots, leaves, and catkins. If you have any further questions, feel free to ask. Best regards,Milan Zubrik

Question

Started noticing damage summer 2022 - gradually getting worse. This year quite extensive damage. Have included photoes from 2024 and 2025, all of same tree. I am interested in identifying the pest and any suggestions on limiting the problem.

Answer

Dear Aasegro, Thank you for your question and the photos you included. Based on the symptoms and the location, it is likely one of the sawfly species — either Pristiphora abietina or Pachynematus montanus. Considering the locality, I would lean toward Pachynematus montanus, but it is difficult to confirm the exact species just from larvae and symptoms alone. As for control measures, the application of a suitable insecticide may help. I recommend consulting your local garden center or agricultural supplier — they can advise you on appropriate products for your area. If you need further assistance, feel free to ask. Best regards, Milan Zubrik
