Bug of the Week: Butterfly Census

With the increased moth activity mentioned last week, there also has been a surge in butterfly activity after the recent rains. In my neighborhood here near Phoenix,  we have seen representatives of almost every butterfly family.

Swallowtails

Because it is missing its hind wing, this one is hard to identify, but I believe it is a pipevine swallowtail.

Whites and Sulphurs

Sulphurs are really easy to spot right now.

We have several fluttering in our yard at any one time, given away by their bright yellow wings.

 

Orange sulphurs aka alfalfa butterflies are particularly common. Some of the females are quite pale.  Right now often seen flitting across six lanes of traffic.

The tiny dainty sulphurs are so cute. This one is visiting a desert marigold.

Hairstreaks, Blues and Coppers

This tiny blue is also adorable. It posed while taking a snack from a milkweed flower.

Hairstreaks grab your attention by wriggling those antennae-like structures on their hind wings. The milkweed flowers are popular places to drink nectar.

 

Brushfooted Butterflies

We saw a few American snout butterflies, but not as many as in the past (previous post).

 

The queens are back.

They have laid eggs for the  next generation on the rush milkweed.

 

Skippers

Last, but not least, the skippers with their uniquely folded wings.

The only family of butterflies not currently represented are the metalmarks.

What butterflies have you found in your neighborhood this month?

Bug of the Week: Moth Extravaganza

Bug of the Week has been re-booted by some recent rains here in Arizona. I’ve been getting notifications of insects that I haven’t seen for a long time. It’s so exciting!

Take for instance this caterpillar a friend found on what she called a pencil cactus, Euphorbia sp.

Here are two more.

See those tiny, stubby horns at the back of the abdomen? That means they are members of the hornworm or sphinx moth family. A little research shows they are ello sphinx (Erinnyis ello) caterpillars.

Ello sphinx caterpillars vary quite a bit in color. Some are green, or a mix of green and brownish-gray.

The adult moths are known for their lovely burnt orange underwings.

Here’s another moth that has been spotted a lot this summer.

Given the memorable common name of black witch moth (Ascalapha odorata),the species is found in the southern United States through Central America and into South America. Flying at night, these relatively large moths can resemble bats. During the day they rest on the walls of houses.

The caterpillars feed on various legumes, including Acacia sp., Senna sp. and mesquites.

White-lined sphinx moths are also active now. They can be active during the day as well as at night.

It is wonderful to watch nature rebound after last year’s extreme heat and drought.

What moths are you seeing right now?

Yarn Doll Moth STEAM Craft for #NationalMothWeek

For National Moth Week, let’s make a yarn doll moth STEAM craft.

Why study moths?

As National Moth Week hosts say in their press release,

  • Part of the Lepidoptera order of insects, moths are among the most diverse and successful organisms on earth.
  • Moths are important pollinators for crops and flowers, and serve as a food source for birds, bats and other animals.
  • Scientists estimate there are 150,000 to as many as 500,000 moth species.
  • Their colors and patterns are either dazzling or so cryptic that they define camouflage. Shapes and sizes span the gamut from as small as a pinhead to as large as an adult’s hand.
  • Most moths are nocturnal, and need to be sought at night to be seen – others fly like butterflies during the day.
  • Finding moths can be as simple as leaving a porch light on and checking it after dark. Serious moth aficionados use special lights and baits to attract them (see our previous post).

Building a moth model not only helps develop both science and art skills — like observation skills — but also fine motor skills necessary for many adult careers.

Yarn Doll Moth STEAM Activity

For the fuzzy body of our model, we’ll use the popular yarn doll technique which entails wrapping yarn around a piece of cardboard.

Typical Yarn Dolls

Gather:

  • Yarn
  • Ruler
  • Index card, 5 1/2 inch long piece of cardboard or file folder (to wrap yarn around)
  • Age-appropriate scissors
  • Card stock or file folders for wings
  • Colored paper for wings (optional)
  • Crayons, markers, or colored pencils to decorate wings
  • Glue stick (to glue colored paper to file folder- optional)
  • Chenille or fuzzy stems
  • Images of moths (hummingbird moths and luna moths if you use the patterns provided)

Instructions:

1. If not using an index card to wrap the yarn around, cut a piece of cardboard or card stock about 5 1/2 inches long by 2 1/2 inches wide (approximately). Cut a narrow slit to tuck the loose end of the yarn in while winding or pin the loose end in place with holding hand while winding.

Slit in card holds the beginning strand

2. Gently wrap the yarn around the center of the card the long way about 25 to 30 times, depending on the thickness of the yarn. The yarn should be snug, but not so tight that it bends the card. Keep the tension as even as possible so all the wraps are the same length. When finished, cut the yarn at the end where started wrapping. Tie the first end to the newly cut end to secure them both together (wouldn’t need to tie the ends if making a yarn doll).

4.  Cut 4 pieces of yarn about 5 inches long to serve as ties to secure the body of the moth. Prior to removing the yarn from the cardboard, slip one of the ties through on the upper edge of the card until there is roughly the same amount of tie on either side of the wrapped yarn. Tie the ends together snugly around the wrapped yarn with a square knot. Then slip a second tie through at the bottom and tie the bottom wraps together.  Tidy the loose ends of the knots by snipping them off now or later when all the ties have been made.

5. Slide the bundle of wrapped yarn to one side to remove it from the cardboard or index card.

6. Tie the third tie about 1 inch from the top of the bundle, creating the moth’s head.

7. Now it is time to make the wings. Decide whether you want to use a plain manila file folder like this hummingbird moth,

Hummingbird moth (also called hawk or sphinx moth)

card stock, or glue colored paper to a file folder (luna moth example).

8. Fold the paper in half and draw one set of wings on it, freehand or using the one of the patterns we provide here:

moth-wing-pattern PDF to download

Place the pattern at the fold where indicated. The narrow bridge that goes to the edge of the folded page will attach the two wings inside the yard body.

9. Cut out the wings. Unfold.

Color the wings now or after assembly. Check images of actual moths for inspiration. Remember that moths often have eye spots on the hind wings.

10. Curl one set of wings slightly and pass through the gap in the yarn body, the fore wings should be toward the head.

11. Tie the last tie around the yarn body behind the wings, to create the moth’s thorax.

12. Cut three chenille stems 8 inches in length to be the legs. Feed them through the yarn thorax on the underside of the wings.

13. Leave the legs free or twist each one around itself to secure it.

4. Add chenille antennae and any other details, such as google eyes (optional).  Tidy the loose ends of the knots by snipping them close.

15. Proudly display your moth.
