Bug of the Week: Queen Butterfly Eggs

The queen butterflies are visiting our desert milkweed plants again.

The female queens are laying eggs on the flower buds, which are apparently a favorite food of the caterpillars.

The eggs are often laid in pairs.

Today they’ve started to turn dark. Does that mean they are going bad?

No, it means the eggs are going to hatch soon…

…into one of these caterpillars, which will turn…

…into one of these beauties!

For photographs of a queen butterfly emerging from a chrysalis, check this previous post.

Bug of the Week: Jewel Beetles

These beetles are commonly called jewel beetles, or metallic wood borers.

Buprestid

The family name is Buprestidae, so they may be called buprestids as well.

Aren’t they colorful? Do you think they are trying to mimic wasps?

It turns out that some of these beetles even fly with their top wings (elytra) closed and only use their membranous underwings to fly. Most beetles, for example our common lady beetles, fly with their elytra up and opened. By flying with their elytra closed, the buprestid beetles look even more like wasps.

The buprestids in these photographs were feeding on flowers in Ramsey Canyon, in southeastern Arizona. These are probably in the Genus Acmaeodera, although it is very difficult to tell one from another.

Bug of the Week: California Sister Butterfly

We had a lot of choices for “Bug of the Week” today, but this beauty won the contest.

California-sister-butterfly

We went hiking in Ramsey Canyon in southeastern Arizona. These butterflies were flying everywhere.

Finally we found some on the ground that were still enough for a photograph.

The butterfly is the California sister, Adelpha bredowii. Can you see the orange tube that is its mouthpart probing the ground?

The butterflies were performing a behavior known as puddling. They are thought to pick up minerals and/or salts from this behavior. Usually puddling butterflies are around actual water-filled puddle or damp ground. This one seems to be probing between rocks.

Butterflies consume a variety of materials besides nectar from flowers. Sometimes butterflies are attracted to rotting fruit (note: this post contains references to butterflies imbibing alcohol).

If you are not offended by graphic vernacular or photographs of butterflies eliminating urine, here is a post about butterflies urinating while they are puddling.

Just goes to show that if you want to attract butterflies, sometimes it takes more than pretty flowers.
