Some beauty to offset a distressing week

This past week in the USA has been rather distressing as far as health and politics are concerned. The COVID epidemic is wreaking havoc and then humans wrought havoc during a procedure intended to be part of a peaceful transition of governmental power. So we can all use a bit of distraction to remind us there is also still beauty in the world and I’ll end my last trio of posts with one more view of hummingbirds – this time featuring the one species that visits my home every year, the ruby-throated hummingbird (Archilochus colubris).

Fortunately, my yard now has several types of plants that offer the hummers natural nectars to complement their primarily insectivorous diet.

The rose of Sharon (Hibiscus syriacus) flowers are a popular feeding site.

They are also fond of the blue-black sage (Salvia guaranitica). My original plants were a gift from birding friend, Gail; now they are growing in four areas of the yard. Sometimes a hummer doesn’t want to hover but uses a nearby prop to offer some less strenuous feeding. And then the bird can close its eyes to thoroughly enjoy the sweet sap.

Hot lips sage shrubs (Salvia microphylla ‘Hot Lips‘), which I got at a garden center, have proved to be popular feeding sites. This is quite a hardy plant.

The hummers also like going to the lantanas (Lantana) and the yellow passionflower (Passiflora lutea), which kindly came to my yard on its own.

 

Another popular plant is the butterfly bush (Buddleia davidii).  Many recommend against planting this bloomer because it can be invasive. However, some garden centers have developed varieties that scarcely seed and that must be what I luckily got as it has never appeared anywhere else in the yard in more than a decade.

It also attracts butterflies, bees, syrphid flies and hummingbird moths, so I’m quite happy with my butterfly bush.

The ruby-throats also do like their nectar, however. After visiting various flowers, they often take a seat near or on the nectar feeder so they can sip at their leisure.

 

They will also do their best to keep other hummers away from the nectar feeder — even when I have as many as three or four feeders available.

They keep an eye out for intruders.

When a rival appears, it can lead to confrontations. Mostly these involve aggressive displays and chasing one another; only very rarely have I seen them actually physically engage.

This past summer, a few laid-back moments occurred when they tolerated one another.

It’s not only the males who are aggressive; female hummers can also be quite protective of feeding grounds. This past year, it seemed that I had mostly males visiting. While a female hummer can have one or two red spots under her chin, usually that is the beginning of a young male developing his ruby-throat.

It can be fun to watch as more spots appear with passing days.

 

Eventually, the males get their fully developed gorget, which can be quite stunning.

The red hue is very dependent on how the light hits their feathers. In some cases, the red feathers almost look black.

  

The hummers take care to groom their feathers.

They take advantage of the rain to have a shower.

There are times when they look a bit scruffy, however. That is when they molt. This process of replacing old feathers with new ones usually takes place on their wintering grounds. This past summer, the hummers seemed to have lingered longer than usual and began molting before their trips further south.

White feathers appear more and more as molting proceeds. And feathers come loose before falling away.

They can look a bit scruffy during this time.

Eventually, they get back to their pretty selves. It always stays fun to watch them flying — at least for me. That is when you can see their tiny feet better.

And you get an idea of how rapidly their small wings move as they hover and soar.

They can beat their wings up to 70 times per second!

It doesn’t seem to me that I’ll ever tire of watching these tiny fliers; they always are entertaining. I hope seeing some photos of them in action have provided you with a brief respite from the worries of the world, too.

Hoppers – insects not frogs!

leafhopper IMG_7673©Maria de BruynMuch of the insect world consists of animals that we usually don’t even see or notice because: a) we don’t know they exist and therefore don’t look for them and b) they are tiny and only well visible with an enlarging lens. But once you get a good look at them, they turn out to be fascinating and sometimes quite attractive. One group of these insects is the hoppers – leaf- and planthoppers, that is, like the gray lawn leafhopper (Exitianus exitiosus) to the left.

As their name indicates, leaf- and planthoppers jump to get around, but they also move by flying, scuttling sideways like crabs, or walking slowly or quickly along plant stems and leaves. Both juveniles and adults are very aware of what is around them and if you do manage to spot one, you’ll see that they are watching you and, for example, may move underneath a leaf to get away from you.This broad-headed sharpshooter (Oncometopia orbona) stayed still for a moment.

About 20,000 different leafhoppers have been described around the world; they feed by sucking plant sap from grass, shrubs, or trees. Planthoppers, some of which look like leaves and may be a bit bigger, also feed on plants.The nymphs (juveniles) are tiny, too, as seen in this photo where you see my fingertip above the nymph of an Acanaloid planthopper .

Leafhoppers, such as the speckled sharpshooter (Paraulacizes irrorata) below generally have wide, flattened and pointy heads with large eyes.

Planthoppers come in different forms and, in tropical countries, some of them are quite unique. While many keep their wings flat against their bodies, the derbid planthopper (Mysidia mississippiensis) looks like Derbid planthopper IMG_0717©Maria de Bruyn (2)a delicate little fly while resting.

Leafhoppers’ hind legs are covered with hairs that help them spread a secretion over their body which is water repellant. Some planthopper nymphs’ back legs have gears that help them jump away in the blink of an eye.

The female broad- headed sharpshooter (Oncometopia orbona) develops white spots on her wings, which are egg brochosomes; these indicate she is ready to oviposit (lay eggs). These spots are made of a white waxy secretion that she places there; they dry to look like “chalky” spots. After she inserts her eggs into a plant, she uses her hind legs to scrape off the brochosomes onto the oviposition site as a way of hiding the eggs from predators.

 

Leaf- and planthopper nymphs can look as if they are completely different insects from the adult forms. As they mature, they begin to look similar to adults but are often of a different color and don’t yet have full wings. Below you see the colorful adult glassy-winged sharpshooter (Homalodisca vitripennis) and below that some nymphs of this leafhopper.

As juveniles, hoppers go through a process called ecdysis. They pass through several stages to reach adulthood, molting and leaving behind their old exoskeleton in order to grow. They are called instars during these stages.

Leafhopper ecdysis IMG_9379©Maria de BruynThe instar stages of the same hopper can look very different from one another, including color changes. Some of the nymphs, with their striped faces and big eyes, look to me as if they’d be great models for cartoon characters or Halloween masks like these coppery leafhopper juveniles (Coelidia olitoria).

Acanaloniid planthopper nymph Acanalonia bivittata IMG_8201©Maria de BruynresPlanthopper nymphs, like the two-striped planthopper (Acanalonia bivittata) and the Acanalonia servillei below, are known for producing waxy strands from their bodies which repel water. These strands also help protect them from predators, who might grab onto the showy white hairs, which break off so that the hopper can escape. The nymphs can ultimately be entirely covered in white wax.

The colors and patterns on the adults can be quite beautiful, especially on the leafhoppers in the area where I live. The planthoppers tend to be white, gray or green. The colors on the coppery leafhopper are wonderful and varied.

As tiny as these insects are, they can be parasitized and play host to even smaller insects. This flatid planthopper (Ormenoides venusta), for example, was carrying red mites that weren’t harming it but hitching a ride. It must be annoying though.

hopper 4 IMG_8036©Maria de BruynsignedI imagine there are many more interesting behaviors to observe with the hoppers. Maybe one day I will get a macro lens so that I can really get some good photos of these cute little insects. In the meantime, as there are several thousand species in North America, I can look forward to finding new ones – with my camera in hand as I wouldn’t be able to see anything but specks on plants without it!
