Mystery Seed of the Week 230

Our mystery seeds this week hardly look like seeds.

The seed pods with immature seeds looks more like it is filled with insects or mites.

The mature seed is reddish-brown one with distinct ridges towards the center of the photo. Doesn’t it look like an insect grub? Mealy bug? Nope, that is a seed.

Do you recognize what plant these insect-like 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.

Seed of the Week: Butter-and-Eggs

Our mystery seeds from last week (229) were from a plant known by several common names, including butter-and-eggs and common toadflax. The scientific name is Linaria vulgaris.

The common name butter-and-eggs comes from the lovely yellow and orange color of the snapdragon-like flowers.

common-toadflax-leavesCommon toadflax is a relatively small perennial  with delicate leaves. It is originally from Europe-Northern Asia and escaped cultivation in North America. It is considered to be an invasive weed, particularly of pastureland, in several states.

In addition to the papery wings around the seeds, they also have warty bumps that can be seen under a microscope.

common-toadflax-flower-1Although considered to be a weed by some, I do have fond memories of “snapping” open the flowers by pinching them in a manner similar to snapdragons when I was a child.

What do you call these plants? Do they grow where you live?

Fabulous New Children’s Book: Beetle Busters

The trees of eastern North America have been having it tough in the last century or so. First the American chestnut was wiped out by the chestnut blight fungus. Then the American elms were killed by Dutch elm disease, which is carried by a tiny beetle. Many forests were ravaged by an outbreak of gypsy moths in the 1980s. More recently ash trees are being killed by the emerald ash borer. In a new middle grade nonfiction book, Beetle Busters: A Rogue Insect and the People Who Track It  (Scientists in the Field Series) by Loree Griffin Burns and illustrated by Ellen Harasimowicz, we learn about another insect that is attacking hardwood trees:  the Asian longhorned beetle.

The North American infestation of Asian longhorned beetles, Anoplophora glabripennis, was first noticed in 1996 in New York City. Because the beetles don’t move far from their emergence site, officials decided the best policy is to destroy all infested trees by cutting them down and chipping them in an effort to eradicate the insects.

Eradication, or complete removal of an organism from an area where it is unlikely to re-occur, has been used with mixed success against insects (see for example, Eradication and Pest Management, Annual Review of Entomology, Vol. 43: 471-491, 1998). In her Author’s Note, Loree Griffin Burns admits that she questioned whether attempting to eradicate the beetles from her community in Massachusetts by cutting down and chipping many trees was going to be a successful tactic. In an effort to find out more, she gathered the materials that would eventually become the book.

Beetle Busters contains information about the life cycle of the beetle, the history of its introduction to North America, details about how scientists are studying the insects, and a in-depth explanation how concerned citizens can get involved. Burns also reveals some information about how cutting down trees changes habitats and some evidence that ecosystems can recover eventually through succession.

This book is another wonderful addition to the award-winning Scientists in the Field series. Although written at the middle grade level, it will be a valuable resource for older readers, as well. If you live in eastern North America and are interested in nature and science, and particularly in trees, this book a must read.
