Mealy Bugs on Oncidium Leaves
bugs feed by piercing the plant surface with mouths that look like
hypodermic needles. As they suck out the sap, they excrete a sticky
substance that coats the leaves. Called "Honeydew", this excretion
first looks like honey, but soon turns to a moldy black. This coating
makes it hard for the plant to breathe and attracts ants.
bugs live in groups and their cotton-like protective sheild makes them
easy to spot.
bugs live for six weeks to two months. Because the adults are on the
move most of their lives, they can cover a lot of plants in their short
lives. Eggs hatch in 5-10 days, or wait longer until conditions are
