Comments.

Anthrax irroratus , like Anthrax georgicus (above), is present in all of North America and reaches Central America and Caribbean islands (Honduras, Puerto Rico). More abundant than its congener, this species has been collected in 15 states in Mexico (including Oaxaca of the Neotropical region not listed above) and all regions of the USA. Anthrax irroratus should be collected in any systematic, long term Bombyliidae sample in Mexico and the USA.
