Notes

The butterfly is common in secondary and montane forest at low to moderate elevations (Alt. 50 - 1000m). Both sexes visit flowers and males frequently come to the banks of streams and puddles to suck water.
There are many issues with this name. f.sarinoides was described as a dry season form of Eurema hecabe. Yata,1994 treated it as a form of hecabe grandis, however we consider it is a form of hecabe hecabe based on the context of the original description. In any case, it was an infrasubspecific name because it was described as a quadrinomial form. However, the name is available from Fruhstorfer, 1910 since Evans,1932 used sarinoides as a subspecies of Eurema lacteola (ICZN Code, article 45.6.4.1).
The type locality and number of specimens were not stated in the original description. According to Yata,1994, a 'holotype' was selected by Corbet & Talbot in NHML. But we consider it to be a syntype because the type designation was not given in the original description. Furthermore, the label states that Corbet & Talbot selected it in 1939. If so, it would be the Lectotype, but this designation was never published.
On the other hand, Shirôzu & Yata,1973 described ssp.inouei from S.Vietnam. The main characteristic is the reduced apical patch of the UnF, and they included the populations of Cambodia and (central) Thailand. However, this is the rainy season characteristic of the continental Indo-china populations. And Yata,1994 misidentified Hinlap as being in Northern Thailand, when in fact it is in Central Thailand near Saraburi and Nakhon Nayok. Thus I treat inouei as a synonym of sarinoides.
The populations from S.Myanmar, W. & N.Thailand have very pale lemon yellow ground color on the upperside. Yata,1994 treated this population as a synonym of sarinoides, however, I consider it to be a good subspecies as Kimura et al.,2011 pointed out. Please see Eurema simulatrix ssp..
