Bicyrtes variegatus (Oliver, 1789)

Avispa de la arena, Sand wasp

Bicyrtes variegatus is easily recognized by the yellow band across the anterior part of the scutellum (Bohart 1996).

This species was observed during the hot rainy season at Garrapatero Beach, forming an aggregation of males, called "sun dances" (Román et al., 2024). There are also records of visited plants: Bidens pilosa (cryptogenic), Croton scouleri (endemic), Galactia striata (native), Heliotropium angiospermum (native), Lantana camara (introduced), Mollugo flavescens (endemic), Scalesia cordata (endemic), Scalesia gordilloi (endemic), Vachellia rorudiana (native), Vallesia glabra (native), Varronia leucophlyctis (endemic), and Waltheria ovata (native).
