occurs (regularly, as a native taxon) in multiple nations
Regularity: Regularly occurring
Type of Residency: Year-round
Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Occasional in southern Florida and Texas; common in Neotropics south to Brazil.
Comments: Brushy fields or open forests in wet areas. In Cuba, host is Picramnia petandra; in Mexico, Alvaradoa amorphoides. Various brushland and forest edges.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Eurema dina, the Dina Yellow, is a butterfly in the Pieridae family. It is found from Panama north to southern Florida. The species is regularly recorded from southern Texas and south-eastern Arizona. The habitat consists of forest edges, brushy fields and open forest.
The wingspan is 32–57 mm (1.3–2.2 in). Males are orange-yellow with a very narrow black border on the outer and costal margins of the forewing. Females are yellow with black at the forewing tip. On the underside of both sexes, three black spots are found on the hindwing. The wet-season (summer) form is paler. Adults are on wing year round in southern Florida. Strays can be found in southern Texas in November and southern Arizona in October. Adults feed on flower nectar of Lantana, Asclepias and small-flowered Asteraceae species in South America.
The following subspecies are recognised:
- Eurema dina dina (Cuba)
- Eurema dina westwoodi (Boisduval, 1836) (Mexico, Costa Rica, Honduras, Panama)
- Eurema dina parvumbra (Kaye, 1925) (Jamaica)
- Eurema dina helios Bates, 1934 (Bahamas)
- Eurema dina bayobanex Bates, 1939 (Haiti)
