Physocephala tibialis, Thick-Headed Fly

2013-12-29: Identified as Physocephala tibialis by Aaron Schusteff, Contributing Editor of BugGuide.


A few weeks ago, I tweeted:

2013-06-11 19:57: Found – or rather one of our cats did – an incredible wasp-mimic fly. Chilling in refrigerator for later identification.

2013-06-11 20:01: The fly looks very similar to /Physocephala/
http://bugguide.net/node/view/7190/bgimage except all-black at first glance. Will examine more closely later.

This is what she found:
Physocephala, Thick-headed Fly

Yes, that is a fly, not a wasp. You can tell it’s a fly from the antennae in the center of the face, instead of the top of the head, the large, rounded eyes that cover both sides of the face, instead of being restricted to the upper part of the head, and the “forked” feet.


For comparison, here’s the all-black Sphex pensylvanicus, Great Black Wasp, to which Physocephala bears, I think, a superficial resemblance. Note the position of the antennae, the location, size and shape of the eyes, and the clawed feet.

Even before I knew what it was, from past experience, I knew that wing venation would be important in identification. By chilling this individual in the refrigerator overnight, I got a few minutes of close-focus macro time to highlight all the key features. Based on comparing the wing venation to other examples on BugGuide, I think this is Physocephala, but I’ve submitted it to their experts for positive ID.

Here are my other photos of this impressive mimic.

Amphion floridensis, Nessus Sphinx Moth

Amphion floridensis, Nessus Sphinx Moth, on Rhododendron viscosum, Swamp Azalea, in my urban backyard native plant garden and wildlife habitat. The two bright yellow bands are a key for this species.

Another lifer moth for me, I saw this in my backyard a few weeks ago. Fortunately, I had my camera with me. Unfortunately, I didn’t have time to break out the flash, or the tripod. This was a fast-moving moth.


Here is a better view of the moth at rest. This is from Flickr member Circeson, taken in Atlanta, Georgia.

Amphion only has one brood as far north as New York, from April to July. The specific epithet floridensis – of Florida – points to its more southern range.

Swamp Azalea flowers are intensely fragrant, reminding me of cloves and maple. The deep, trumpet-shaped flowers are perfectly suited to this moth, which hovers in front of each flower while it sips out nectar with its long tongue from the nectaries at the base of the corolla.

Sphinx Moths, Family Sphingidae, are medium to large moths, generally colorful, and certainly eye-catching in flight.
