Plant galls, also known as cecidia, are among the most fascinating phenomena in nature. They arise through interactions between plants and gall wasps, gall midges, gall mites, aphids, cicadas, fungi, bacteria or nematodes and are remarkable for the astonishing variety of forms they can take.
This website provides extensive information about cecidology, the science of plant galls. In addition to a large photo gallery, you will find detailed information about the various gall inducers and their host plants, as well as a continuously expanding glossary containing many specialist terms relating to plant galls and their inducers.
The photo gallery contains several thousand photographs covering plant galls, fungi, slime moulds, insects, spiders, butterflies, wild bees, beetles, and many other animals and plants from the natural world around us.
The photo gallery also documents many other organisms from the natural world around us, including fungi, slime moulds, insects, spiders, butterflies, beetles, true bugs, wild bees and numerous other animal and plant species. Most of the photographs are taken under natural conditions and are intended to show both the diversity of species and the beauty of the natural world around us.
Whether you want to identify plant galls, are interested in gall wasps, gall midges or gall mites, or simply want to discover the diversity of nature, I hope you enjoy exploring my website.
