Mating behavior ( Figs. 2 View Figure 2 A‑D)
Several specimens of Megacyllene angulata were observed on a single specimen of Doliocarpus dentatus (Aubl.) Standl (Dilleniaceae) . The vine was cut, but it was still fixed on the canopy of a large tree of Luehea cymulosa Spruce ex Benth. (Malvaceae) . In the cut part of the vines (about 1.5 meters above the ground) there was sap dripping and several male and female specimens of M. angulata clustered in this region ( Fig. 2A View Figure 2 ). The specimens showed a repetitive behavior climbing from the cut part to a region 3 meters above the cut and vice‑versa.During this movement there were several copulation attempts, in which males frantically pursued females ( Fig. 2B View Figure 2 ). Most of the copulations, when initiated, were interrupted by aggressive behaviors of other males biting especially the pronotum and antennal base of the male specimen in mating ( Fig. 2C View Figure 2 ). Couples, which escaped the attacks, climbed to the upper part of the vine (about 2 meters above the cut) and remained immobile on the region of the vine not directly exposed to sunlight ( Fig. 2D View Figure 2 ).
