I saw really many in the Yucatan peninsula just recently. Those in full sun did not look very healthy. The old pseudobulbs were dead and dry, while those growing in the Mangroves in the shade had many live growths and were spiking. The leaves were yellow.

Those that I saw attached to the trees in front of the beach hotels in Tulum looked too dried up and declining.

Those were all Myrmecophilas, possibly tibicinis. I do not think there are Laelias in the area.

Maybe in full sun they do OK with extra watering. But I was in Tulum, Quintana Roo for 8 days. It did not rain once. Sometimes it was humid but every night was very windy and relatively dry because of that. I have photos that show that. Myrmecophilas there are more common than Brassavola nodosas, Catasetums, Oncidium cebolletas.

I think Laelia superbiens may take more sun and draught than Myrmecophilas. For sure it has plumper pseudobulbs vs hollow and has more and thicker roots
