Unless otherwise noted, we are following BugGuide.net for taxonomy of arthropods.
We would have liked to use ITIS as the exclusive authority on taxonomy, unfortunately it is
lacking many entries for insects and spiders.
- BugGuide, a large online photo collection of insects and spiders from North America. Use the advanced search to find subjects from Texas.
- Integrated Taxonomic Information System (ITIS), a partnership of North American agencies to provide a consistent taxonomic hierarchy.
