A very unique type of Spider nest that I've not seen used before. It was about 1 cm in diameter and has a circus tent-like structure with a second layer of webbing added on over the first layer. It was located on the under side of the leaf. The eggs must be under the flat surface of silk. The spider was nowhere to be seen, so it's creator remains a mystery.
Semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico, 2,200 meters.
On 22 August, I went back to the plant with this nest and cut out a piece of the leaf with the nest on it. I've put it in a terrarium to see what emerges. After all the conversations and ideas from everyone, I decided to try something: on 29 August, I lighted up the nest from the opposite side of the leaf with a LED light (ie: no heat) to try to photograph the silhouette of whatever was inside. It actually worked and it looks like eggs inside and some have already hatched into spiderlings. You can see some of the little bodies with their 8 legs (picture 3), especially on the upper left side. None are emerging yet so maybe they stay inside until their first molt, as do many spiderlings. Can't wait to see them and give you all a photo!
