Back to the lek tree - Lycus simulans - male - female

Back to the lek tree - Lycus simulans - Male Female
Santa Rita Experimental Range Station, Florida Canyon, Pima County, Arizona, USA
July 25, 2013
Size: ~13mm
After the hike up florida canyon, we returned to the parking lot. Alice Abela had a mating pair of yellow lycus walking on her hand, which she graciously let us photograph. gathering_2013

Moved
Moved from Lycus.

Moved
Moved from Lycus simulans.Moved it back because we read about the apparent distinction and these seem rather to have the long thin rostrum of loripes. We'll await further instruction.But thanks for the lead.

Lycus simulans
joeCicero has ID'ed similar pair from same area:

 
the rostrum of Lycus loripes
the rostrum of Lycus loripes is about 3x longer than that of L. simulans in this picture. Nowadays, that by itself isn't definitive enough, but until someone looks into this species complex more carefully, L. simulans stands as the nomen for this morphotype.

More important is their biology...they are congregative as adults at flowers, where males force themselves under the female wings to access and partake of their secretory glands, and they also congregate at prime oviposition sites for mass egg-laying which, consequently, produce bivouacs of huge numbers of larvae. Prime oviposition sites include holes of various sorts that allow access to root systems, fallen logs, dead yucca/agave/sotol rosettes and so forth. They undoubtedly feed on the microflora of moist dirt, as well as soft, fragile fungi, but that has yet to be confirmed.

 
These were on an oak in the parking lot of SERA,
Margarethe can say what kind of oak. There were some kind of galls in the acorn caps and on the acorns of that oak and there were all kinds of bugs in there feasting on some kind of exudate: three kinds of Lycus (at least), several scarabs, several wasps, several moths, and more! It was wild. There were Lycids and Cerambycid Lycid-mimics and moth Lycid-mimics. Every time we got back to the station, we went back to this tree.

Anyway, we'll move these back to simulans. Thanks. What do you think of this pair which is currently placed in loripes?

Here's Joyce's image of the galls

 
Emory oak
Margarethe identified it as emory oak (Quercus emoryi). It attracted a great deal of attention at BG gathering_2013, including my own. There were two species of Cerambycid Lycus mimics and one Cantharidae Lycus mimic there. I did not notice the moth Lycus mimic (I was probably fooled!). Many of them have already been posted from the gathering.
