In relation to L. figueresi, it is smaller and can be distinguished by wing color, patterns, punctate, and sternal and genital characteristics.

[3] A female L. aeneiventre is recognized by its unique striped pattern on the front part of its mesothorax, the pattern of punctures on its front scutum of its middle thoracic segment, its larger size, its hair, and its slightly yellow wings including the membrane, veins, and stigma.

Generally larger than males, it has a metallic dark-green head and a clypeal length greater than that of its supraclypeal area, which is slightly rounded and bulges.

It does not have a frontal line ridge from below the base of the antenna to about half the distance between its antennal sockets to its median ocellus, and its lateral ocelli are slightly nearer to each other than to their compound eyes.

Its black metasoma is shiny and mostly smooth, its brown-tinted black legs are shiny and flattened on the front surface with a well-defined rim raised above the surface of the plate at the base of the tarsus, and its sharply rounded wings have dull yellow membranes with smokey tips.

In comparison to a female, its compound eyes on its dark-green head converge more below and become wavy, and it has punctures on the clypeal area, vertex, and frons.

Compared to the females, the male's wings are clearer, its veins are nearly brown, and its yellow to golden-yellow hair is sparser.

On flat ground, entrances are perpendicular to the surrounding land and descend straight down with only slight deviation or extend 10 to 18 cm in vertical banks.

Females emerge from their nests in September and mate with other males; afterward they become inactive, only provisioning their cells during favorable weather.

[3] The majority of solitary female L. aeneiventre found between June and October are mated with oocytes beginning to develop and sperm in their spermathecae.

In solitary female nests, normally created at the beginning of the dry season, offspring emerge in late January and February.

They sit partly out of the entrance to their nest, most likely warming up their muscles needed for flight, and then forage until 2:30 to 3 PM.

This activity occurs on clear or partly cloudy days yet stops during rain and low hanging clouds.

Plants provide it with pollen and nectar as food for both themselves and their larvae, while parasites invade their nests and affect their survival.

[10] The diet of L. aeneiventre from larvae to adults consists of loaves of pollen mixed with nectar.
