Habitat. This species is usually associated with floating, emergent or submerged vegetation in the margins of ponds, lakes, lagoons and marshlands, in unshaded areas (Drake & Chapman 1958; Poi de Neiff & Carignan 1997; Fontanarrosa et al. 2004; Fernández & López Ruf 2006; Torres et al. 2007). It has also been found in rivers (Rodrigues et al. 2021b), along the vegetated margins of streams in standing or slow-moving water (Drake & Harris 1943; Torres et al. 2007), and on urban rain pools without aquatic vegetation (Fontanarrosa et al. 2004). This species was collected in a pond with Salvinia minima Baker and in streams with Azolla filiculoides Lam. and the bryophyte Ricciocarpus natans L. (Corda) (Ronderos et al. 1969).

Poi de Neiff (2003) reported the first collections of L. lacuniferus from Iberá in association with Salvinia biloba and Pontederia azurea. At the INR, specimens were collected from the vegetated margins of Medina Lagoon, in unshaded places, and in standing or slow-moving water along the margins without aquatic vegetation of Pay Ubre Chico Stream, in shaded places. Two specimens were taken at lights in Colonia Carlos Pellegrini.
