Halocoryza Acapulcana
"The Halocoryza Acapulcana beetles can be found shores of islands in the Atlantic ocean, Pacific ocean, Indian ocean, Sea of Cortés, Caribbean Sea, and the Gulf of Mexico, primarily in inter-tidal lagoons on the edge of mangroves. Acapulcana adults are most commonly found in March and August. Acapulcana are capable of flight, but are slow runners. Adults are attracted to light, and are nocturnal predators. Halocoryza Arenria
