Seed of the Week: Canyon Hackberry

Anna correctly identified our mystery seeds from last week as being from a hackberry tree. These particular seeds came from the netleaf or canyon hackberry, Celtis reticulata.

Canyon hackberries are found along streams, washes, and in canyons throughout the West.

They are for the most part shrubby, small trees.

hackberry-knobby-barkThe bark on the trunk is often covered with warty knobs and ridges.

hackberry-branch-with-berriesThe branches can be droopy.

hackberry-leaf-veinsThe leaves, however, are quite striking.

hackberry-leaves-close-betterThe tree gets its common name “netleaf” from the prominent veins in the leaves.

There are also netlike ridges on hackberry seeds, which is one way to recognize them.

canyon-hackberry-drupesThe fruit are red-orange drupes that when ripe are a favorite of birds, which is why people grow them in landscapes.

Another good reason to grow netleaf hackberry trees is that they are the larval food of the hackberry emperor butterfly, Asterocampa celtis.

What kinds of hackberry trees grow where you live? What do you think of them?

New Resource for Sharing Poetry and Science!

Today we have a new resource for sharing science poems with children.

Science poems? Yes, like “Comet Hunter” by Holly Thompson, which she reads in this video:
 

 

The resource is The Poetry Friday Anthology for Science (Teacher’s Edition): Poems for the School Year Integrating Science, Reading, and Language Arts by Sylvia Vardell and Janet Wong.

 

The K-5 Teacher Edition has a poem for each week of a school year (36 weeks) for Kindergarten through 5th grade, for a total of 218 science poems by 78 poets. To help extend the poems, every one is accompanied by a 5-step mini-lesson with connections to the new Next Generation Science Standards.

student-editions

Separate student editions are also available for each grade that have 36 poems (plus a few bonus poems), each on a separate page and illustrated with line drawings.

Why combine poetry with science? As the authors suggest, a poem can be read and enjoyed by children with a range of reading abilities. The use of sensory language and vivid imagery is likely to bring a new depth to scientific concepts. Also, poems that are read aloud and savored can make science topics more memorable.

One benefit that the authors don’t mention is that children who regularly hear poetry on different topics just might be inspired to write poetry of their own. I know I was:

Milkweed Beetle
By Roberta Gibson

Gently touch a milkweed beetle,
And it will give a squeak.
Bet you didn’t know an insect
So very small could speak.

All in all, The Poetry Friday Anthology for Science makes sharing science poems on a regular basis throughout the year a breeze. Aren’t you ready to see where that could take your children?

Bug of the Week: Beetle Life Stages

Most of us recognize the life stages of butterflies, but what about beetles?

 

scarab-beetle-grub-100For example, would you know this larva would turn into a beetle?

scarab-beetle-grub-200Although the head capsule may look a bit like a caterpillar, this is a beetle larva commonly called a white grub. It lives in the soil and will turn into a type of scarab beetles called a “June beetle.”

seed-beetle-pupa-111

Here’s an odd one. I found this in a mesquite seed pod. It is about the size of a small grain of rice.

seed-beetle-pupa-100Turning it over, it has two dark spots, which are the developing eyes. This is the pupal stage of a seed beetle or bruchid.

seed-beetles-eggs

The seed beetles lay their eggs on seeds of legumes like mesquites, within the seed pod. Can you see the white eggs that look like sesame seeds attached to the larger brown mesquite seeds?

The larvae, which look like small versions of the white grub above, feed inside the seeds and then cut their way out to pupate. You can see the holes in the seeds and the round caps on the left of the photograph where the larvae cut their way out.

seed-beetle-close

Soon the seed beetle pupa will become an adult like this one and go look for a place to lay its eggs.

Have you ever found beetle immatures before? Where did you find them?
