Despite a widespread belief that ants produce formic acid, the habit is confined to only one of the 20-some ant subfamilies, the formicinae.  This is among the most abundant subfamilies, containing the familiar carpenter ants and field ants, and is recognizable by the single constricted waist segment and an acid-dispersing nozzle called the acidopore at the tip of the abdomen.  The most recent myrmecos.net upload covers a variety of formicine species from Arizona, Illinois, and South Africa.

Friday Beetle Blogging: Pasimachus ground beetle

My apologies for the lack of blogging the past few days.  I’ve been taking some time away from posting for the holidays, but I’ll be back next week.  In the meantime, here’s a Pasimachus ground beetle…

The wingless hangingfly

I lived in California until a few years ago, and one thing I enjoyed about the Golden State was the unique insect fauna, full of bizarre and relictual creatures.  One of the oddities was the wingless hangingfly, a leggy mecopteran that lurks in the coastal grasslands.

The insect above was photographed indoors.  I made a makeshift studio out of various bits of debris lying around the lab: a matte black notebook for a backdrop, a jar to hold the grass upright, and the white lid to a styrofoam cooler propped a few inches above the insect.  An off-camera strobe fired up at the cooler lid (and away from the hangingfly) provided bright diffuse light and set the soft tone of the image.

Flea

I don’t ordinarily hang around animal carcasses.  But every now and again I’ll brave a fresh roadkill to shoot the parasites as they jump ship from the cooling body.  Fleas and lice are fascinating creatures, and as they are hardly ever photographed alive I can capture some unique images just by staking out a common subject that most people would not think to shoot.
