I was going to transfer a native stingless bee hive, or if lucky, split it into two. Alas, on opening, it had been attached by syrphid or hover fly. Normall...

Thanks Christa. I think the Ceriana ornata are the ones that were hanging around the hive. Anything else that looks like a wasp or hoverfly, I don't care about.

Maybe I am mistaken, Andrew, but the fly I am referring to, is the HIVE SYRPHID FLY Ceriana ornata. It is the common fly that enters the weak hive, it's maggots have 2 posterior spiracles which looks like 2 dark pointy parts at their rear end.
The common hoverfly that I often see in my garden, has a different appearance. It may help with keeping an eye out.

Those damn pine boxes have caused me huge amounts of grief Barbara. I don't even blame the Hover/Syrphid flies. They don't bother a solid hive and the larvae eat lots of aphids. The hard learned lesson is in the boxes.

Thanks, Andy, for putting up stuff about disasters as well as successes. It helps to know what to look out for. Sometimes one can get the idea that nothing ever goes wrong, so it's good to see how you cope with problems as well as successes.

I am paying the cost of using treated pine Christa. It rots. While I taped it up, I guess they got in. I only delayed because I was scared to do a complete transfer. I won't make that mistake again. Hardwood only from now on. In other news, the Syrphid fly is the same thing as a Hover fly - my friend against aphids. You're dead right: compromised hive disaster.

Very sad Andrew, did you see a syrphid fly around the hive, did you identify the larvae as syrphid fly larvae. Most times they look for a weak joint on the hive and lay eggs at that point and enter the hive. It pays to check your tape around the hive regularly as they can get under it and they smell the honey. They can drop to the ground and hatch in the soil as well.
Apparently you can put out a trap to catch the fly.
We have not had them enter our hives before, but did have small beetle attack and lost a couple of our hives to that bug.
Don't give up and try to keep an eye out, the hives are most prone when they have been opened.
