👉 Phascolionidae are a group of small, spherical phragmoids found in many phragmites species. They have a smooth, rounded surface and can vary greatly in size from 0.5 to 3 cm (0.2 to 1 inch). These phragmoids play an important role in the survival of the phragmites grass, which is a vital part of the ecosystem as it serves as a food source for many other organisms.
