Did you ever consider making a huge feeder (like 100-200ml or so) that can be plugged to the wall of a formicarium
Yes, such a project is in process. Designing the perfect mating connector and way of actually interfacing with the side wall and hole are very big challenges, however.
The liquid feeder portion itself works perfectly, and I've been using ones that plug into the side of a formicarium or foraging area for the past 9 months. The ability to connect to a variety of holes that people make is the main setback, and I haven't invested too much time in that part yet.
That said, this will definitely become available in 2017.
Hey Terry - does the 8 pc come with the 2017 Sunburst formula? What improvements or changes were made in the new formulation?
Yes, the 8 pk does include a 120 ml bottle of Sunburst. This bundle variation is currently only available on the US and Canada Amazon sites. It also exports from the US Amazon site to many countries around the world.
The Sunburst 2017 changes are very minor, and if Sunburst is working well for you, you shouldn't notice any change whatsoever in receptivity. The changes are technical, primarily for the improved preservation and physical material properties of the liquid. The label is now also waterproof.
Regarding the Camponotus "vomit," I frequently observed this when ants would eat the old Formula Blue 100, they would have a designated spot in the nest where there were many small, blue-colored stains. I have no idea why they did this, but my best guess is that either the nest was too dry, and they were attempting to hydrate it, or they were removing the excess moisture so they could ingest a higher concentration of other vital nutrients. Either way, given the ingredients of the food and the intermittent frequency of the behavior, I don't expect any bio incompatibility with any species of Camponotus.
