I also use http://zipcodezoo.com/ for searching base on location/ISP : ... and on the 48 species of Aulacophora genus, i try to search & see one by one... and woow! they looks very similar for me.. :))

AshishNimkar.., I don't know the identity of the insect in the photo, and i try search on gooogle, there are many foto that similar to this yellow-bug, they named cucumber beetle, or cucurbit leaf beetle, squash beetle etc...! and I also see many for "Scarlet Lily beetle" that looks more red with black head. and i read on wikipedia, that mention the "Scarlet Lily beetle" is quite dependent on the presence of lilies plant.

thanks..., the spider may be: Mangrove St. Andrew's Cross Spider -female (Argiope mangal Koh, 1991)

I mean colias is a genus. all they from family of Pieridae. but check this links for sure:
1. http://en.wikipedia.org/wiki/Phoebis_sen... (Cloudless Sulphur)
2. http://en.wikipedia.org/wiki/Sulphur_but... (Sulphur butterfly)
3. http://en.wikipedia.org/wiki/Eurema (grass yellow butterflies)

I mean colias is a genus :) but c'mon we checkagain this yellow butterfly.

@Alicelongmartin, I believe: the name of this spotting this is already correct. this is a butterfly from the family of Eurema (grass yellow) and the species is Eurema hecabe.... There are three (frequently looks very similar) families of yellow butterflies: Eurema (grass yellow), Cloudless Sulphur (Phoebis Sennae) and Clouded yellows (Colias)...

At first, If your butterfly from Indonesia, I'm not sure this "orange sulfur (colias)" but i believe: this is from the family Eurema (grass yellow butterflies in the family Pieridae). and from its special characteristics at the beginning of the forewing: it have two spots! The species of your butterfly is Eurema hecabe (common GrassYellow).

There are three families of yellow butterflies: Please check again and make compare the family of Eurema (grass yellow) x Cloudless Sulphur (Phoebis Sennae fam) and also Clouded yellows (Colias fam).

thanks for the ID, Ashish

done :))

Thanks Ashish..., although it is difficult to find confirmation of its presence in East Java, I also believe this this Asura Sp.
