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.
