(Hemiptera) 

These insects are shown alphabetically, by family or superfamily, genus, and species. If you see an error, please let me know via the contact tab at the top of the page.

Aphididae: Oleander Aphid (Aphis nerii)

All three photos show Oleander Aphids on Horsetail Milkweed. You can see more of that wildflower on a separate page. Oleander Aphid females produce new young female aphids, no males required. In other words, all of the aphids shown in these pictures are females.

Aphididae: Mealy Plum Aphid, Hyalopterus pruni

The following summary is based on this web page. Hyalopterus pruni spends its winters on species of Prunus (including plum and apricot trees) and its summer on reeds, preferably the Common Reed. The aphids are usually green but can also be a dull red. In the spring, the eggs hatch on the host trees. In the summer some of the aphids grow wings and fly off to find reeds. Late in the summer, some aphids on reeds grow wings and seek out trees where they can lay eggs. The new eggs hatch the following spring. As part of this cycle, the aphids molt and leave behind their former exoskeletons. Those are the small white things you can see in my photos.

While this aphid is not usually considered to be a species attended by ants, the web page I mentions offers photographs of such behavior. As do my photographs.

Aphididae: Uroleucon

Berytidae: Stilt Bug (Jalysus?)

Stilt bugs have long, slender legs, along with long antennae with slightly club-shaped endings. I found these ones hanging out on Linda Tarde flower spikes. Stilt bugs in the genus Jalysus feed on Evening Primrose Family members, so the examples shown here are probably of that genus.

Cercopoidea (superfamily): Froghoppers

The adult members of the Cercopoidea are known as froghoppers, thanks to their impressive leaps. The plant-sucking nymphs, or spittlebugs, cloak themselves in a protective secreted foam that resembles spittle. 

Cicadidae: Cicadas

There are multiple species of cicada in New Mexico, in more than one genus. Two of my photos show what people usually find: the empty exoskeleton of a cicada nymph. The adult emerges from a slit in the back. In one image the branch has been bent back to provide a view of the slit. The image with the nymph exoskeleton upside down shows it in the position in which I found it. Such discarded exoskeletons are known as exuviae (usually plural).

Coccoidea (superfamily), Dactylopiidae: Cochineal Bug (Dactylopius)

If you notice small white puffy areas on the surfaces of prickly pear pads, you're looking at female cochineal bugs and their nymphs. To be more exact, you're looking at the protective covering those bugs create. In prehistoric southern Mexico, cochineal bugs were raised on groves of prickly pears and harvested to produce a vivid red dye. If you pinch one of the fuzzy patches between your thumb and forefinger, you'll see the dye source (carminic acid) for yourself. Today, cochineal bugs are a source of natural red food coloring, so you may have ingested some cochineal bug juice at some point.

Coccoidea (superfamily), Coccidae? Scale insect (cf. Saissetia)

There are about 8,000 described species in the superfamily Coccoidea (or infraorder Coccomorpha, if you prefer). I have no idea which species this may be; my limited ID is courtesy of an entomologist. As a lay person, my only accomplishment was to notice numerous black spots on (but not in) barberry leaves, and that the spots were all the same size, the same shape (oval), and shiny. By the way, "cf." is science-speak for "looks a lot like."

Gerridae: Water Striders

There are more than 1,700 species of water striders on our planet. Most people credit their ability to walk on water to surface tension alone, but it helps to have legs with hydrophobic surfaces.

Largidae: Bordered Plant Bug (Largus)

Largidae: Bordered Plant Bug (Stenomacra marginella)

Lygaeidae: Small Milkweed Bug (Lygaeus kalmii)

Pentatomidae: Green Stink Bug? (Chinavia hilari?)

While this individual resembles a green stink bug, Chinavia hilaris, the coloration doesn't seem quite right to me.

Pentatomidae: Say's Stink Bug (Chlorochroa sayi)

Reduviidae: Bee Assassin (Apiomerus)

The common name for Apiomerus, bee assassin, refers to their habit of waiting in flowers for an insect to come by. Then they earn their name. For more on this bug's M.O., see the description for the leaf hopper assassin bug, below.

Reduviidae: Pale Green Assassin Bug (Zelus luridus)

For a description of this bug's M.O., please read about the Leaf Hopper Assassin Bug immediately below.

Reduviidae: Leaf Hopper Assassin Bug (Zelus renardii)

In these images, the head deserves a closer look. The upper part is the main part of the head, but the lower part is a folded-back stylet (hollow dagger). There's a small vertical gap between the two. Assassin bugs unfold the stylet and plunge it into a victim, inject digestive fluids, and do a Vactor on the victim's innards. A well named group of bugs, but one that does in countless harmful insects each year. 

I found the adult working over a patch of Emory's Baccharis. The nymph was on a Russian Olive.

Rhopalidae: Scentless Plant Bugs (Harmostes)

Rhopalidae: Boxelder Bug (Boisea trivittata)
