Spotting

Sorry bayucca, I am just a spotter. For the ID I usually search from the common book of insect, not so expertise. especially the dart, is easily confused without detail explanation for the difference.
really thanks for your help :)

Quite unusual to do an ID for you, Yeung. Usually you are an excellent spotter, photographer and IDer. So, I am a little bit careful with this one. It seems for me like being a female Cephrenes acalle. But I only can see one of the four wing surfaces. So, please, verify yourself!!
