A brief skim of that plant family does not indicate that there is a presence of specialized cells designed to attract ants. I strongly suspect that what you are seeing is water that is traveling straight up the xylem and out plant pores. Depending upon where you see the droplets, it could be guttation. Ants and aphids do not have a permanent relationship. Aphids can multiply and thrive just fine without them and vice versa. All the ants really care about is that they have a ready supply of carb rich liquid to ingest; it doesn't much matter where it comes from. The aphids benefit from this relationship as do the ants. Aphids, when being tended to by ants, will produce a sweeter honeydew in order to insure their guards' attentiveness. These kinds of ants will also protect any other sugar producing insect, tree wound, nectar producing floral gland, etc. The ants don't care from which source their carb fix comes....they will protect an insect or a plant.

When I first saw the photos it appeared that you may have posted pictures of two different vines. The one on the wall and most of the others look like one vine. The fruit and the leaves in the background in picture 5 on the left appear to me to be a different plant and a grape of some sort.

Possum grapes are a kind of wild grape that grows here in Okla. I grew up eating them. My dad made Possum Grape (PG) wine out of them and my mom would made jams and jellies and we'd just eat them. They are sweet when ripe. They are ripe when they are purple and soft. I love them. And actually just ate a few yesterday and took a vine clipping to start another patvh of them at my house. This is the time of the year when the vines start producing the grapes. Yes, they do grow like crazy and the birds do love them but just enjoy their fruit. Pick the grapes and freeze them in a freezer bag until you get enough to make whatever it is you want to make. I think that the vines are beautiful with the curly tails and large leaves. I'd love to build a porch with a frame for them to grow around and over to provide a shade. If you wanted to do this... I'd suggest that to keep them at bay, to put up a fine woven netting that opens in sections. Reasons: 1) To keep the vines off your head. 2) To keep the grapes and bird droppings off if everything. 3) the sections would allow you to open up and pick the grapes. Just as an FYI & if u dont mind some information....Plums, peaches and blackberries are also out right now if you love wild fruits like this Okie Country girl does. Hahaha and Morel mushrooms come out between March & April. Watch the Oak trees. When the leaves are about the size of a quarter than go out hunting for them in wooded ares that are near a body of water, they will be found growing out in the shady ooen areas, up from the dirt amongst closely growing SHADY trees that have moist surrounding soil, though very little to no grass growing. Put them in a large bowl of water and slosh around to clean, repeat this 2-3 times. Do NOT throw the water out. Either take it back to where you found to mushrooms growing and dump it there or find an appropriate place as I described above and put it there. The water will contain the spurs which are what the mushrooms grow from. Give back to nature what you have taken from it. ;) After rising, towel pat dry, quarter them up. Make a batter of flour/salt/pepper/ baking powder/egg & water to the consistency of waffle batter. Dip them, than deep fry in oil til brown and floating. Than invite your loved ones over to enjoy them with you. This is something my family has done for many many years. It's a traditional thing we do. They are a treat for us, they are a delicacy and are actually very expensive if you were to or even could buy them. Now that my dad is at that age where it's too tasking to walk far... the responsibility of finding them each year has been passed to me. :) I hope thos helped you and I hope you didn't mind the lengthy added info. Just wanted to share in hopes that you or someone reading might use the info to enjoy the smaller things in life.

The black specks are worm poo. As far as getting rid of them....if you have time in the morning, check the undersides of leaves for tiny sparkly round things attached...those would be moth eggs, most likely. If you get rid of those you'll have prevented the hatching of more worms. The least toxic (to people and plants and animals)solution to any caterpillar problem is BT spray. I am going to misspell it, but it's a liquid with bacillus thurengesis in it. These are bacteria that will kill the caterpillar about 24 hours after they take a bite of the leaf. Assuming they do so as baby caterpillars, you won't see much damage, and eventually the population will drop off to just a few every now and then. Follow the directions on the bottle. It is supposed to be safe to harvest same day. I still rinse my maters well, just to be on the safe side. BT is generally considered acceptable by most organic gardeners...(certainly not all). Another thing you can do is to encourage birds to pick off the insects and worms...but if you do, you'll need to pick your maters at first blush and let them ripen in a window indoors.
