| Popis: | Dr. H. T. Fernald (4) gives as synonyms of Sphex aberti (Hald) the names Ammophila yarrowi Cress. and A. moontezuma Cam. This species was one of the first of our wasps to which has been ascribed the rernarkable habit of using a pebble or other suitable object as a tool. The observation was made by Dr. S. W. Williston (9) in 1892 on specimens determined as A. yarrowi. He considered the habit so unusual that he refrained publication for a time thinking the act might be doubted. It is now an accepted fact, though somewhat variously interpreted, and has been witnessed by a number of careful and accurate observers in this and other species. |
