Mallada basalis has a length of 10–15 mm, and typically has a pale green colour.[12] Its translucent, veined wings are iridescent in natural sunlight.[12] Specimens can be identified by a green pterostigma present in the hind wings that is not present in Chrysopidae of a similar appearance.[12]
The first confirmed sighting of Mallada basalis in New Zealand was in 1940 on the Kermadec Islands, though evidence of the species may go back as far as 1908.[14] In 2010, a specimen was identified on Tiritiri Matangi Island in the Hauraki Gulf, and the first specimen in Auckland was identified in 2016.[12] By 2020, Mallada basalis was present across the Auckland and Northland Regions.[12] As of 2020, it is unclear if this species self-introduced to New Zealand, or if it was introduced due to human activity.[12] The impact of this species on New Zealand is currently unknown. No native Chrysopidae species have been previously described from mainland New Zealand; their presence may control agricultural pests such as aphids and mealybugs, or pose a risk to native insect life.[12] Many lacewing species were imported to New Zealand between the 1920s and 1970s, however none successfully established populations in the country.[15]
