Leafhoppers
Wikipedia: a leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. N.B. I'm not an entomologist so I can only guess these are leafhoppers and not planthoppers.
If anybody visits this page and knows different, even better the species names, please let me know!
Planthoppers
Wikipedia: a planthopper is any insect in the infraorder Fulgoromorpha: in the suborder Auchenorrhyncha. As with the leafhoppers, I >think< these are planthoppers. If anyone knows for sure, please let me know.
