Note 3 — Chapter X · THE EMPUSA
Alexander Teixeira de Mattos translation
The Ammophila is not the only one to sleep in this singular position, which is copied by many others—Anthidia,3 Odyneri,4 Euceræ5—and mainly by the males. All grip a stalk with their mandibles and sleep with their bodies outstretched and their legs folded back. Some, the stouter species, allow themselves to rest the tip of their arched abdomen against the pole.
