Summary
| Description |
English: Oak apples or galls (Ø 7–8 mm). Keila, Northwestern Estonia. Galls are made of plant tissue and form when an insect secretes a chemical that causes interference with normal plant cell growth. Adults lay eggs in expanding tree buds and leaves in the spring. The gall provides a safe home as well as food for the young wasps. Each gall contains only one young wasp. The larvae then feed, pupate and emerge from the gall as adult wasps after 2–3 months. Fortunately, galls do not cause significant damage to trees. |

NOTE: This image is a focus stacked image consisting of 45 images that were merged using Helicon Focus. As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.
