Ops,sorry..not sure how to difference them,hehe.Oh,no wonder i saw it like scrubing at the soil while i took the picture,im about 10cm away from it,manage to zoom abit.Jus using the normal lens and thats as shallow as i could go hehe,moreover i use flash and worry about it getting scared and sting me or something haha.Thanks for the infovespa_bicolor,how do you know what type is it and including its scientific name too?
