Bug of the Week: Hollyhock Visitors

This week the hollyhocks will catch your eye here in Arizona. Tall, with large, striking red, pink, or white flowers, the hollyhocks are a favorite.


Certain insects and arachnids also seem to prefer hollyhocks.

Shiny metallic-green flies were resting on the leaves this morning.

Aren’t they pretty?

Any ideas what they were doing?

Called long-legged flies, the small green flies are predators waiting to catch other insects for food.


Tiny, pale green leafhoppers like this one are a meal for long-legged flies.

Another fly I found isn’t quite so welcome.

This tiny yellow and black fly is an adult leafminer. The fly will lay its eggs in the hollyhock leaves. The larvae will feed between the upper and lower surface of the leaf causing a winding light-colored tunnel. Fortunately the damage is relatively cosmetic (looks only).

Other creatures already hard at work on the bottom leaves of some of the plants are spider mites.

The spider mites make fine webs like spider webs, hence the name. In our hollyhocks, the mites quickly build up, causing the leaves to turn yellow and die.

Hopefully, some predators will show up that eat spider mites. Here’s a sign that at least one predatory insect is about to make an appearance. Do you know what the stalk is?


I’ll give you a hint:  it is on the underside of the leaf (I flipped it over).


Bug of the Week: Crab Spider

Did you see the spider in the cactus flower photo in last week’s post?

I have circled it here.

The spider is a common type of spider that sits on flowers and waits for food to stop by. Spiders of this group are called crab spiders, probably because their legs are directed forward like a crab’s. (Maybe they should be called “grab spiders” LOL!)

I found another one this week, which has picked a fruit fly off of a lemon.

Can you see the little red-eyed fruit flies peeking out of the hole?

The really cool thing about crab spiders is some of them can change color to match the object they are sitting on, although it can take a day or two. Does this one look a bit yellow? I think so…

There are a number of good nonfiction books about spiders for the picture book set, like Are You a Spider? by Tudor Humphries

Spiders also abound in picture book fiction. Here are two classics we enjoyed a great deal:

The Very Busy Spider by Eric Carle

Diary of a Spider by Doreen Cronin (Author), Harry Bliss (Illustrator)

Adults can find a few good books on spiders, too.
Biology of Spiders, 2nd Edition by Rainer F. Foelix

Bug of the Week: Overwintering Grasshopper

Did you ever wonder where insects go for the winter?

Sometimes insects spend the winter as adults.  We found this one hiding in a pile of leaves when we were doing some yard work.


A few weeks ago we found another grasshopper that looked very similar hiding in an old bird’s nest that had fallen down. I guess by having old nests and old leaves lying around, we are helping out our insects. Who would have thought?
