What is that?
 

My Orchid has a leave that has what looks like water drops under the leave on the edge. What's that? Please can someone tell me ?

could be insect egg sacs. I don't think I could positively ID it even with a picture, but I'd remove it with a cloth.

I have some phrags that do that. Don't know the reason for it, but they seem happy so I don't worry about it. I think someone here once called it happy sap or happy juice.

When your plant is happy and well watered the leaves will "perspire." Nothing to worry about!

Yes, many orchids produce this sap. My Phals do under their leaves around the edge. But certain bugs can leave sticky stuff too. As long as you don't see any bugs and your plant is healthy don't worry about it. When I first saw this Happy Sap I thought I had bugs but found out it was normal. Good luck!

The plant has a (new) spike about 4-5 inches long. Many new leaves and air roots galore. This plant gave me flowers non stop since January. I recently repotted it and it's very healthy until I saw that dew or whatever that is. I'm afraid to touch it. I haven't seen bugs no. BUT I have few times seen what looks like MOSQUITOS, flying about and very few. But they aren't always there.

I added a pic

It's looks normal. I wouldn't worry about it.

My phals do this too! Glad to hear it can be normal as long as no insects are involved.

I'm guessing the mosquito things are gnats.

Orchid sap and sweet too. Take a taste. Some say it is just from osmotic pressure in the plants vascular system and others say it is from bugs biting the leaf. I don't come anywhere near over-watering my plants and yet this is common. Especially on new and growing flower sheaths. But, really, taste it. It is quite delicious.

gnats? so should I be concerned? how can I rid of them? why are they flying about?

I'am afraid to taste it since I read somewhere is the bug's waste.. know what I mean? Yikes ! That's why I'm researching this subject.

The picture you showed us tells us that it is what some call happy juice. It is a sweet liquid from the plant. The biggest issue with it can be sooty mold which thrives on the sugars in the sap. It's not bug poo. Here's some pics. It happens mostly on flower sheaths as these are somewhat thin and it is easily exuded from the tissue.

Gnats don't harm orchids. They don't feed on them. You might be seeing gnats that live in the potting meadium. They like moist environments. Or it's just a coincidence. Where I live we have tons of mosquitoes, gnats and fruit flys that get inside from the doors being open.

Bugs that you would be concerned about would be scales and other sucking insects. They suck the plant juices from the orchid. They can leave a sticky residue behind but in my experience they don't leave it in droplets like in your picture. Like I said before, many orchids secrete this sap. Like James said, the sheathes secrete this liquid a lot. New growths do too and so do Phalaenopsis leaves. My two NoID Phals secrete it in little drops around the edge on the bottom side of the leaf like in your photo.

It is not bug poo like James said. Don't worry about it. You said your plant is healthy with no bugs so its fine. Gnats or mosquitoes would not cause this Happy Sap. Good luck!

Yes i repeal my bug concern. Definitely not bug related from the photo. Their stuff is usually white or brown/black.

Thank you for the pics and ur prompt reply. I have seen tiny tiny white bugs tho crawling as I noticed today some leaves are looking almost like leather, wrinkly-ish. Today was their watering day, I soak them for 10-15 mnts as usual. I wonder if I'm ever going to learn how to read these Phals :( I don't want to loose this plant, means the world to me specially now that has a spike going :(

You guys are so nice ! thanks so much for your words of encouragement and warm welcome. :) I hope I did ok tho since I decided to clean the leaves off that sticky stuff. I looked it up on home remedies for plants, with soap, a bit of corn oil and even pepper. So I cleaned the leaves with my hands making sure it's dry at night, with a soft air (cealing fan)circulating the room. I think it says to do this daily for 2-3 weeks. Or at least til I notice bugs are gone. :)

The happy juice is normally sweet as james points out. This is the same reason why some insects are attracted to it.
