1. To an extent - Drosera
dew from what I remember is a mixture of various polysaccharides which trap water in their structure to give the "glue-like" consistency. Water might dilute it a little bit, until it washes away.
2. Depends on the Utricularia
. There's something like 230 or 240 different species, and many have rather different cultivation requirements. It also depends on your terrarium conditions. Does it heat up a lot due to being closed, for example? In general the humidity doesn't bother most Utricularia
, but other conditions may be quite impactful for them.
3. Depends on the pond water. You want something fairly stable in terms of water chemistry, a bit on the acidic side, and without a lot of free nutrients (nitrates, phosphates, etc). Take a look at the page here, which also applies for aquatic utrics. http://www.sarracenia.com/faq/faq5050.html
4. Definitely not
. In my experience Utricularia
are particularly low ppm plants. High ppm makes most terrestrial species melt. Some of the ones from sect. Orchidioides
will tolerate elevated ppm for a while (such as when fertilizing) but will not do great if they are constantly exposed.
5. Yes, and it depends on the species of Utricularia
you have. I'm sure you could culture some microorganisms (Paramecium? or stuff like vinegar eels) for the smaller terrestrials and aquatics. The really big ones (U. humboldtii for example) would probably eat mosquito larvae or daphnia. MaxSea fertilizer tends to work more or less on many terrestrial and epiphytic species, if given in the right dosage.
6. Maybe, but like carnigrower said it sounds a little dry.
7. They diverged pretty long ago (not closely related at all imo). Most recent common ancestor seems to be on one of the branches of the clade Pentapetalae, before superrosids and superasterids diverged. See here: https://en.wikipedia.org/wiki/Eudicots
"Potential has a shelf life."
