Good Spot for Zyxomma obtusum

I have been observing Zyxomma obtusum lately. The grassy streamlet/drain shown below is a good site for Z. obtusum. During day time, Z. obtusum is totally absent from the site. Starting at 6.30pm in the late afternoon, Z. obtusum shows up one by one..... by 7.00pm, I could see more than 30 individuals of Z. obtusum hanging arond the site! What a view! I was totally thrilled to see so many Z. obtusum non-stop patrolling the drain/streamlet...... it looks like they were having great party!





Below are two photos to show Z. obtusum on wings having good time at the above habitat.
