Seed of the Week: Red Bird of Paradise

Our fascinating seeds in a pod from last week’s mystery were from a red bird of paradise, also called pride-of-Barbados (Caesalpinia pulcherrima). In Phoenix it is sometimes mistakenly called a Mexican bird of paradise, which is a different plant.

The red bird of paradise is a popular landscape plant in Phoenix. It grows to be a tall shrub during the summer, with lovely orange/red flowers.

It has lacy compound leaves.

Originally from the tropics of South America and the West Indies, the red bird of paradise is frost sensitive and loses its leaves in the winter. Many people cut the plant nearly to the ground in the winter, but it grows back readily when the weather gets warm again.

The floral structure is unusual, with very long stamens.

The stamens are the male parts of the flower that produce pollen.

The flowers are favorites of bees, wasps, hummingbirds and butterflies. The plants are thought to be pollinated by butterflies.

Once pollinated, the plant produces seed pods,

and these interesting ridged seeds. Note:  Some websites have indicated the pods and seeds may be poisonous.

You probably won’t see the seeds in the pods once they mature.

The dried pods burst open on the plant and shoot the seeds. Cool!

Red bird of paradise plants have a number of interesting features, including having nectaries outside the flower that produce nectar for visiting insects.

Have you ever seen a red bird of paradise?

Bug of the Week: Pallid-winged Grasshoppers

Grasshoppers are moving in Arizona right now.

One of the most common species is the native pallid-winged grasshopper, Trimerotropis pallidipennis.

It can be difficult to identify grasshoppers because members of a single species vary a lot in color. The two grasshoppers in the photographs are within a few feet of each other, but notice how much darker the top one’s wing bands are (it isn’t just the lighting). Grasshoppers often blend into the background so well that you don’t see them until they jump and fly.

Pallid grasshoppers feed on desert grasses and when the grasses dry up, they move or “disperse” to areas with more food. According to this article, pallid grasshoppers have been found flying at altitudes of 3000-5000 feet for long distances. In one record in 1966 pallid grasshoppers from the western United States were found in Hawaii. That’s a long flight!

Are grasshoppers still active where you live? What colors do you see?
