Spider orchid facts for kids
Spider orchid is a cool name for many different types of orchids! These plants get their name because some parts of their flowers look a bit like a spider's legs or body. It's a common name used for several orchid groups, but most often, people are talking about the Caladenia group of orchids.

What Makes an Orchid a "Spider Orchid"?
Spider orchids are known for their unique look. Many of them have long, thin petals and sepals (which are like outer petals) that stretch out, making them look like a spider's legs. These parts can be very delicate and sometimes have interesting colors or patterns. This special shape helps them attract specific insects for pollination.
The Caladenia Orchid Group
The Caladenia group is a large family of orchids found mostly in Australia. There are hundreds of different Caladenia species, and many of them are called "spider orchids." They often grow in forests or woodlands and can be quite small, sometimes only a few centimeters tall. Their "spider" look helps them stand out in their natural homes.
Where Do Caladenia Orchids Grow?
Most Caladenia spider orchids are found in Australia, especially in the southern and western parts. They love to grow in sandy soils or among leaf litter on the forest floor. Some species are very rare and only grow in tiny areas, making them special plants that need protection.
Other Orchids Called Spider Orchids
While Caladenia is the most common "spider orchid," several other orchid types also share this nickname because of their similar appearance.
Corybas Species
Some species from the Corybas genus are also called spider orchids. These are often small, ground-dwelling orchids.
- Corybas macranthus
- Corybas trilobus
Dendrobium tetragonum
The Dendrobium tetragonum is another orchid known as the Common spider orchid or Tree spider orchid. This type often grows on trees or rocks, which is why it's sometimes called a "tree spider orchid."
Bartholina burmanniana
Bartholina burmanniana is a beautiful orchid from South Africa that also has the spider orchid name. It has very fine, feathery petals that give it a unique, delicate look.
Ophrys Species
Several Ophrys species, found mostly in Europe and Asia, are known as spider orchids. These orchids are famous for mimicking insects to attract pollinators.
- Ophrys fuciflora (Late spider orchid)
- Ophrys sphegodes (Early spider orchid)
Brassia Genus
Members of the genus Brassia are often called "spider orchids" too. These orchids are known for their very long, narrow petals and sepals that can look like the legs of a large spider. They are popular in cultivation because of their striking appearance.
