Zusammenfassung: | Melanoplus tequestae Hubbell is a small, brachypterous, forb-feeding grasshopper inhabiting sand scrub and xeric oak forests of central Florida. Pair formation between silent males and females occurred when the male slowly approached the female or waited until her general activities brought her closer to him. Females raised their ventrally colored hind femora and extended their tibia to signal non-receptiveness. There was no apparent courtship before mounting, but after mounting males shook their hind femora before copulating. Mounting and copulation could last from a few hours to 1 1/2 days. Male aggressive signaling was by bursts of femur shaking. /// Melanoplus tequestae Hubbell es un pequeño braquíptero saltamonte habitando malezas en terrenos arenosos y bosques de cedros adaptados a ambientes secos en el centro de la Florida. El apareamiento entre machos silenciosos y hembras ocurrió cuando el macho se acercó lentamente a la hembra, o esperó a que las actividades generales de ella la trajera más cerca de él. Las hembras levantaban su colorida fémur trasero ventralmente, y extendían su tibia para señalar que no eran receptivas. Aparentemente no hubo cortejo antes de montar, pero duspués de montar, los machos sacuden su fémur posterior antes de copular. Montaje y coplación pudiera durar de unas pocas horas a 1½ dia. La señal de agresividad del macho son sacudiones del fémur. |
