Bug of the Week: Intro to Snails with Escargot

A writing friend recently introduced me to the cutest fiction picture book about a snail, Escargot by Daska Slater and illustrated by Sydney Hanson.

You can see for yourself. Sophia reads the entire book in this video:

Although I usually feature nonfiction, fiction children’s books like this one may also inspire us to investigate scientific questions.

For example:

Do snails eat carrots?

Yes, they do. When we raised them years ago, our brown garden snails ate carrots. It was easy to find videos of other kinds of snails eating carrots, too.

What is a snail’s mouth like?

A snail scrapes off food with a radula, which has teeth like a saw blade.

Do snails really have eyes?

Yes, but not where they are shown in the book.

The snail eyes are the black spots at the ends of the upper feelers or tentacles.

What are those other things sticking out of a snail’s head?

The lower feelers or tentacles help the snail taste or smell its food.

Where do snails come from?

 

Adult snails lay eggs.

Tiny baby snails hatch out of the eggs, complete with tiny shells. Their shells get bigger as they grow.

Would a snail really like vinaigrette on its salad?

No, the vinegar in the vinaigrette could harm a snail.

Did reading the book Escargot give you any questions about snails? If so, we’d love to hear them.

Bug of the Week: Aphid Fly, Dioprosopa clavata

Aphids are a sure sign of spring and with aphids come a host of other insects that depend on them for food.

Take this insect near the bright orange-yellow oleander aphids on the rush milkweed. It looks a bit like a wasp with its ultra-thin “waist”, but its actually a fly, becuase it has two wings rather than four.

A few seconds before it laid an egg among the aphids.

It is Dioprosopa clavata, a type of flower fly (family Syrphidae). Another common name is aphid fly, because its larvae eat aphids. In fact, if you look up a bit on the stem to the right of the fly, there’s an older flower fly larva.

Here’s a closer view of another flower fly larva sitting on the bud of a rush milkweed flower.

The larva will pupate soon and become an adult aphid fly, so the cycle will continue. It is the life cycle of a family of specialist flies, based entirely on a few aphids on a milkweed plant.

Bug of the Week: Spring Flower Action

The spring flowers resembled busy airports this week.

The desert marigolds were abuzz with insects, including this photo-bombing honey bee.

The red and black bug is a charcoal seed bug, Melacoryphus lateralis.

The brittlebush flowers were also teeming with insect life.

 

Many of the flowers harbored false chinch bugs.

Some were hiding underneath.

Along with numerous honey bees, the flies were active. This is the black flower fly, Copestylum mexicana.

Is it a bee or a fly?

This one is another kind of flower fly that mimics a bee.

This plant bug’s spring finery matched the flower.

It’s an exciting time of year in nature.
