I'm super-happy about this because it's the first orchid I've ever gotten to rebloom that isn't a phalaenopsis. I got it in mid-May last year, when I was just starting to collect orchids and still very clueless about their care. It's a trooper for putting up with me Hopefully the luck will continue with the other orchids I've acquired since then.
If anyone knows the name of this guy, please let me know
a complex hybrid. That said, search for the orchid works and look at Oncidioda Copper Scarab 'Brass Brethren'. This is what came to mind when I saw your posted picture. But also see Oncidioda Jimbo 'Swarm' (same site). They pump out 4000+ copies of the crosses they clone, many of which end up in the pot plant trade. Many more are "grown out" by mid-size vendors.
Very nice and congrats on re-blooming this. There are so many in the Oncidium intergeneric group that look similar. It is impossible to know what the name is for sure. So it should remain as a NOID and if you like you can give it a name of your choice for your own use.
