Ok I guess I am land locked so help me here. What is a sea wasp?
Sea Wasps are smaller, almost invisible jellyfish that are attracted to light. They think your dive light is the Moon, and they are ascending to feed. They are hard to spot even though they can range from 1/2" to the very rare 3 feet long. Most have bodies the size of a clear square-ish egg and 4 thin tentacles extending 8" down.
In 1000+ night dives, I may have been zapped once. It's nothing more than a sharp quick pain and a lingering owie for most divers. Try not sucking them into your snorkel. I have seen that and it had a bad outcome for both parties. Jellies can not pop you through something even as thin as pantyhose. There are a few different ointments that you may use to protect yourself in advance. Benadryl works as an after treatment.
Do I "prefer" night diving? I never miss one. I hate resorts that trumpet that "their night dive" is on Wednesday. Bad sign.
We amazed the staff at Atlantis in Philippines in that we wanted to go out every night for 7 days straight. They gladly made it happen, but we were viewed with mild curiosity. It was spectacular.
We go to CoCoView every year. I have seen better diving, even in the Caribbean, but the access 24/7 to a great shore dive (night dive) is what brings us back. Getting in that 5th dive on any given day is quite a way to end the day. Then- there's the people who go back out at 4 a.m.
Ask them if they like night diving!
