Question
Answer
Hi Tina, than you for your requestt. This is caused by Andricus quercuscalicis, a small wasp species. It's called a Knopper gall. The female wasp lays her eggs on the acorn cup in May and injects a special fluid into it. In response, the oak tree forms a strange growth – a green, irregular lump about 2 cm long, known as a gall. Inside this gall, the wasp larva develops. With best regards Milan Zubrik

Question
Chcem len vedieť o akého chrobáka ide a či je nebezpečný pre ovocné stromy. Veľkosť asi je 5 - 7 cm.
Ďakujem
Answer
Dobrý deň, ďakujeme za dotaz. Je to fuzáč drsnotykadlový a vyvíja sa v odumierajúcich a starých stromoch. A áno, aj v niektorých ovocných stromoch, napríklad v orechu. Viac o ňom nájdete v našom atlase. S pozdravom M. Zúbrik
