Bug of the Week: Burrowing Bug

Can you figure out what order this fuzzy black insect belongs to?

burrowing-bug1

Is it a beetle or is it a true bug? It looks and acts like a beetle at first glance.

burrowing-bug2

Do you remember the characteristics of a true bug?

  • Triangle-shaped scutellum (link shows more clearly) in the middle of the back, between the top of the wings
  • Wings half hardened and half membranous
  • Sucking mouthparts (like a straw)

Although you can’t see the mouthparts, this is a true bug. It is a relative of the shield or stink bugs called a “burrowing bug,” Family Cydnidae.

As their name suggests, these bugs burrow underground to feed on plant roots.

Otherwise, not all that much is known about them. Do you think that is because they are mistaken for beetles?

Mystery Seed of the Week 170

Mystery seed is back for number 170!

mystery-seed-170-1

This mystery seed was hard to extract from the fruit that had dried around it.

mystery-seed-170-fruit

Perhaps you can recognize the dried fruit instead.

Please let us know if you have an idea what the plant might be.

 

Edit:  The answer is now posted.

Bug of the Week: Glasswing Butterfly

Today’s featured insect was inspired by a new children’s picture book, Glasswings: A Butterfly’s Story by Elisa Kleven.

Have you ever heard of a glasswing butterfly?

The common name glasswing may refer to a number of different types of butterfly throughout the world, but we are going to focus on those of the tribe Ithomiini found in Central America. The wings lack scales and have other properties that make them transparent except for the edges.

Like our monarch butterfly, the glasswing larvae feed on a toxic plant (in this case nightshades) and become distasteful themselves. There is some evidence that the adult butterflies may be protected by chemicals, as well.

Also like the monarch, these butterflies migrate, flying from place to place.

Here’s a short video showing some glasswing butterflies, one drinking from a flower. Isn’t it interesting how the different colors show through, almost like a picture frame?

Aren’t they amazing? It makes me want to travel to Costa Rica right now, what about you?
Have you ever seen a glasswing butterfly?
