Southwestern Research Station, 1 month later: Change

Well, I had hoped to post more while out here, but as I should have predicted, being outdoors in the Chiricahuas took up most of my time. I have a good backlog of stories though, which I will be posting once I return home in about a week. In the meantime, an update on the past few weeks is below.

A spectacular Gibbifer californicus, the aptly named Pleasing Fungus Beetle. A member of a mostly tropical group that just reaches the southwestern U.S. It sure pleased me! (Herb Martyr, Chiricahuas, AZ)

I arrived at the Station one month ago, and while much of it looks the same, a lot of changes have occurred. Spring has certainly sprung, with many trees and other plants flowering; this in turn has brought out the native bees, wasps, flies, and other pollinators, which have proven to be excellent photography subjects! The temperatures have also warmed up, with daytime highs generally in the 70s and 80s (F). This has brought about the emergence of even more interesting insects, as well as the appearance of more colorful birds and lizards. I recently had the chance to take some much better shots of those animals and will be writing a post on Chiricahua birds (wasn’t this supposed to be a bug blog?) at some point.

Pallid-winged grasshopper, Trimerotropis pallidipennis, at San Bernardino NWR. This is a common, widespread western desert grasshopper, found from British Columbia south to Chile, but this encounter was a first for me!

What about the Orthoptera? The last time I posted here, there weren’t many species out, and most were still nymphs. That is most certainly not the case any more. Most of those species that were nymphs are now adults, and I’ve run across a lot of other species starting to emerge too. It is still quite silent at night, but during the day the open oak-juniper woodlands surrounding the station are abuzz with the crepitating flights of Arphia conspersa, the speckle-winged rangeland grasshopper. Down in Portal, riparian areas and small ponds are alive with the chirping of Gryllus field crickets and the trilling of Mormon ground crickets (Neonemobius mormonius). The real chorus will happen during the monsoon season starting in July, but I will be long gone before then unfortunately.

Rustler Park in the high Chiricahuas. Note the ponderosa pines and douglas fir, as well as evidence of a fire in the background.

With the arrival of other interns/volunteers, some of whom possess cars, I have been able to go somewhat further afield on a few occasions. Barfoot Park and Rustler Park, mountain meadows in the high Chiricahuas with plants and animals more characteristic of the Canadian/Hudsonian fauna, were very cool and quite different from habitats around the station. I’ve also made it into Portal a couple of times, which has a desert scrub environment that is tricky to explore due to the prevalence of spiny mesquites and cacti, but well worth the effort. Going further, I had the chance to visit San Bernardino NWR, a preserved area right on the Mexican border that holds a rich marshland contained within desert – a tantalizing combination of habitats that was rich in grasshoppers. In addition to buggin’ forays, I was also lucky enough to partake in a few odd adventures – caving in Chiricahua crystal cave and invasive bullfrog eradication in a manmade pond (which yielded a lot of cool insects as well!).

Scott’s Oriole (Icterus parisorum)

Much change has occurred here in a month, and although I’m sad to be leaving just as spring is setting in, I’ll definitely be back – when, who knows, but the Chiricahuas beckon.
