Bug of the Week: Flatid Planthopper

One from the archives:

This little insect might not have ever caught my eye if it had been on a plant.

Of course, against the brown twig and soil you can really see it.

This is a flatid planthopper, Family Flatidae.

The adults and nymphs suck fluids from plants.

Planthoppers can hop, as their name implies, but often they simply shuffle to the other side of a stem when approached.

You can see the citrus flatid planthopper move in a characteristic way at the end of this short video.

The flatid planthoppers appear to have a soft white glaze, which is actually a powder of wax they produce themselves. Some scientists have suggested that the wax helps the insects escape from predators. The white wax may make the insects look moldy, so birds think they are unpalatable.

I wonder if anyone has looked into the properties of those waxes. Are flatid planthoppers easily overlooked insects with overlooked potential?

Bug of the Week: Sharpshooters

I found an odd-looking creature this week.

Can you see the bulging eyes?

Even the nymphs, like the one in the photograph below, have them.

Most insects that have large eyes are predators, like praying mantids and dragonflies.

These sharpshooters feed on plants. They use their large eyes to avoid being eaten. When something approaches the insects, they quickly scoot to the other side of the twig or branch. If the potential predator comes even closer, they leap away.

Big eyes can come in handy for prey as well as predators.
