Euaresta jonesi is one of the species of Euaresta with the anterior notopleural seta present, the apex of cell r₂₊₃ with 2 marginal hyaline spots, and the ground color of the thorax dark brown. In wing pattern it most closely resembles E. bella, bellula, stelligera, and stigmatica, from which it differs in having more extensive hyaline areas. In particular, there is a large quadrate hyaline spot in cell br near its apex, that extends completely across the cell and broadly touches both veins R₄₊₅ and M (Foote et al. 1993).

Biology
Euaresta jonesi has been reared from female flowers or developing seeds of Ambrosia chamissonis (Lessing) Greene, the only host plant recorded to date (Foote 1966, 1984, Harris & Piper 1970).

Economic Significance
Euaresta jonesi is not known to be economically important. It presumably reduces seed production by A. chamissonis, but the latter, commonly known as beach bur, is not a major weed or important source of allergic pollen (Goeden & Ricker 1974).
