Part III: How many species of daddy longlegs?
Longlegs fact #3:
With more than 6,500 species, Opiliones represent the third largest order of Arachnida. The largest arachnid order is mites/ticks (order Acari) with more than 50,000 described species, followed by spiders (order Araneae) with more than 40,000 species. For a better frame of reference consider this: there are approximately 5,700 species of mammals in the world while there are more than 350,000 species of beetles in the world.
Almost every time I travel to a new place in Central America to collect harvestmen, new species are collected. So there’s plenty more work to be done in understanding and describing the diversity of this group.
Below are more photos of harvestmen from Costa Rica.
