General distribution. Costa Rica, Panama, the Greater Antilles, the Lesser Antilles, Colombia, Venezuela, Suriname (as Microvelia amrishi Makhan, 2014), French Guiana, Brazil, Ecuador, Peru, Paraguay, Argentina, Uruguay (Makhan 2014; Cordeiro & Moreira 2015; Moreno-R et al. 2018; Motta et al. 2018).
Habitat. Microvelia mimula lives in a wide range of aquatic habitats. It was found at the margins of unshaded pools of various sizes (including urban rain pools without aquatic vegetation and artificial ones), ponds, lakes, lagoons, marshlands, ditches and drains, with sparse or dense vegetation (Hynes 1948; Torres et al. 2007; Fontanarrosa et al. 2009; Muñoz Riviaux et al. 2010; Rodrigues et al. 2021a), and along the almost always vegetated margins of unshaded and shaded streams and rivers in standing or slow-moving water (Fernández & López Ruf 2006; Pereira & Melo 2007; Torres et al. 2007; Muñoz Riviaux et al. 2010). This species has also been taken at lights (White 1879a, b; McKinstry 1937).
At the INR, M. mimula was collected from the margins of the Iberá Lagoon in shallow waters with emergent and floating vegetation (Estévez et al. 2003). During the present study, this species was collected from margins with dense floating, emergent and submerged vegetation and filamentous algae in lentic habitats (Galarza Lagoon, Luna Lagoon, Iberá Lagoon, ponds, artificial wells, marshlands, roadside ditches and flood-prone areas) and lotic habitats (Isirí Stream, Carambola Stream, Lobo Cuá Stream, Corriente River and artificial channels), in unshaded areas. This species was also found in shaded habitats in standing or slow-moving water along the margins without aquatic vegetation of Pay Ubre Grande Stream and Pay Ubre Chico Stream, and at the margins of ponds, marshlands and roadside ditches with or without aquatic vegetation. Some specimens were collected in a swimming pool in Concepción de Yaguareté Corá.
Remarks. Microvelia mimula is one of the most widespread species of water bugs in the INR. It was often collected together with M. hinei.
