Bug of the Week: Brown Soft Scale

We have some dwarf pomegranates growing in our back yard.

Last week I noticed one of the fruit was pale and had brown spots.

A closer look revealed some insects. Do you see them?

I have to admit the brown discoloration makes it difficult to pick out the insects.

Here’s a better look. Those ovals with the brown stripe down the middle are brown soft scales.

How did they get there? The stage of scale insects that move are the hatchlings, called crawlers. Usually they don’t move far, but sometimes the crawlers may travel on animals or be dispersed on the wind.

Once on a suitable plant, the crawlers insert their sucking mouthparts into the plant and remain in place throughout the rest of their lives. Not a very exciting existence, if you ask me.

Do I need to be concerned about the scales? Nope, because I noticed the black lump. It doesn’t look like much, but it is the offspring of a parasitic wasp. Soon those scales will be history.

If you’d like to see the wasps and some other organisms that use scales for foods, see oak scales at Nature Posts.

Bug of the Week: Insect Eggs

Have you ever wondered about where insects go in the winter?

It turns out that different kinds of insects have different strategies for avoiding the stresses of winter.

I found two examples of one strategy this morning. The tactic is for the female insects to lay eggs in the fall. Eggs are often more resistant to cold and drying out than other life stages and can be hidden in protected places. In the spring, the eggs hatch and start the cycle again.

This cluster of eggs is on a grapefruit leaf. It will be interesting to find out what kind of insect they hatch into.

Here is the second example. It is an egg case of the Mediterranean mantis,  Iris oratoria. The female mantis has added a layer of hard foam around her eggs to further protect them.

Have you found any overwintering insects lately? What was their strategy to protect themselves from the cold?

Bug of the Week: Favorite Photographs of 2014

What better way to ring out 2014 than with some photographs of insects?

Looking back over the last twelve months, I found I haven’t taken as many photographs of insects as in years past. I did, however, take quite a few of true bugs this year, like these boxelder bugs.

Not the best shot, but I thought these milkweed bugs were amusing.

Maybe it was color that caught my eye, as with this orange on orange composition.

Bees are always fun, although they are usually in motion. Check out this leafcutter bee collecting pollen.

She has filled her scopa (hairs on the underside of the abdomen)!

This one is reminding us that bees feed on nectar as well as collect pollen.

Parasitic wasps can be colorful.

Paper wasps sometimes take a break to do some cleaning.

What year is complete without a ladybug?

But the butterflies always give the brightest displays. This is a paper kite.

White Peacock Anartia jatrophae

Here is a white peacock catching some rays.

You can get some beautiful close-ups in butterfly exhibits.

The unexpected shots in your own back yard, however, are always the most treasured.

Do you have a post of your favorite nature photographs, too? Feel free to leave a link in the comments.

Happy New Year!
