Thanks for the reminder!
Now that I have my automatic watering system in place I can get it misted every day (so I stop forgetting and letting it go bone dry!)
At my current house it is most popular with the bees and mud-dauber wasps! (set up one separate just for the mud-daubers filled with good wet soil after they stole half my emergent pond plants soil! the bees like the clean sand)
And a tip I had heard for butterflies is to add some salt (non-iodized sea salt) as the males need it (salt and minerals), its fairly hard to (normally) find in nature (not so much now that our roads are covered in salt each winter...but still worth a try)
