Mystery Seed of the Week 256

 Our mystery seeds this week are hard to forget.

mystery-seeds-256-1They are shiny and roughly triangular.

mystery-seeds-256-23They are also fairly small (the white object is a grain of rice added for scale.)

Do you recognize what plant these seeds are from? If you choose to, please leave a comment with your ideas.

Mystery Seed answers and new Mystery Seeds are posted on Tuesdays.

The answer is now posted.

Bug of the Week: Moth Caterpillars

As our last post for National Moth Week, which is going on now, let’s take a look at some caterpillars that turn into moths.

1. Family Saturnidae

Remember these large moths from our moth identification post I? As you might imagine, the caterpillars are also large when they are mature.

Take the captive-reared cecropia moth caterpillars in this video, for example.

They will form a cocoon and then eventually emerge as a cecropia moth.

Zephyr-Eyed-Silkmoth-Caterpillar-4589Saturnid moth caterpillars can have various spiky projections, like these Zephyr Eyed Silkmoth larvae that look thorny (Automeris zephyria).

2. Family Sphingidae – called sphinx moths, hawk moths or hummingbird moths

Sphinx moth larvae or caterpillars are sometimes called hornworms.

white-lined-sphinx-caterpillarExamples include the white-lined sphinx caterpillar,

manduca-larva-largeand tobacco or tomato hornworm larvae.

hornworm-caterpillar-0051Hornworms are named for the spike-like projection at the rear end of the abdomen.

manduca-rustica-212Some species have a similar shape, but may lack the spike, like this rustic sphinx caterpillar.

3. Family Erebidae -Tussock and Tiger moths

hickoy-tussock-moth-caterpillarTussock moth caterpillars often have tufts of “hairs,” like this hickory tussock moth caterpillar.

woolly bear caterpillarTiger moth caterpillars are also “hairy.” The woolly bear caterpillar is a common example.

4. Family Noctuidae – the noctuids or owlet moths (Moth Identification II post)

Noctuid caterpillars are often mostly bare.

budworm-2This budworm larva has a few hairs, but they are sparse.

cabbage-looper-larva-leafCabbage looper caterpillars also have only a few sparse hairs.

Note:  many of the looper caterpillars belong to the family Geometridae (which means “earth measurer.”)

There are many, many more fascinating caterpillars that turn into moths.

Have you seen any interesting caterpillars lately?

Seed of the Week: Angel’s Trumpets

Our mystery seeds from last week were from a plant commonly called angel’s trumpets, Brugmansia sp.

angels-trumpets-plant

These large shrubs or small trees are originally from South America, although I admit that I have only seen them growing in greenhouses.

Brugmansia are called angel’s trumpets because of their extraordinarily large, hanging trumpet-shaped flowers. Plant breeding enthusiasts have developed beautiful hybrids and cultivars with flowers of many colors and shapes.

A relative of datura, all parts of these plants are toxic.

mystery-seed-255The photograph of the seeds from last week was by Klaus Beyer at PublicDomainPictures.net.

Have you ever grown this plant? What color were the flowers?
