Lost specimen returns (and promptly leaves)

deformed male
Today I caught the missing Scudderia mexicana deformed male! Previous attempts had been thwarted by the animal, which refused to eat my baits and positioned itself in a heavily tangled region where its songs bounced off the leaves (making it impossible to locate by ear).

I found it in a conspicuous position on a palm frond; there was another rose pruning today and this may have disabled its auditory camouflage. Fortunately, the species seems largely oblivious to danger unless touched/blown on and I easily caught and repositioned it to a shorter rose bush. It calmed down and resumed singing very soon after I left it alone with a pollen cluster.




Edit: after the sun set, I saw the katydid slowly approaching a nearby taller bush and then making an attempt to fly onto it. It landed near the tall bush's basal stem (too deformed to fly) but I failed to recapture it. Evidently the short bush is not suitable for some reason; perhaps the animal somehow senses that the foliage is insufficiently dense? I have also previously seen females feeding on the short bush's roses and then promptly fleeing after satiation.

I both win and lose the staring contest

The lethargic Scudderia mexicana  deformed male has vanished for the past several days. I still cannot find it and probably never will.




Assorted news:

I have discovered another "aphideating party" composed mostly of what appear to be adult Cycloneda sanguinea.

Phaneroptera nana lives in my area! I thought it was a small pure green Scudderia sp. until a Bugguide expert corrected me yesterday. Today I took some more pics of nana and have put them below. They are on the same bush as the coccinellids.

Unfortunately I will probably be unable to do any katydid or coccinellid posts for quite some time due to troublesome circumstances relating to the front yard.

Staring contest continues


News:

Scudderia mexicana deformed-wing male (pictured above) is still doing fine. Yesterday the rosebushes were pruned and nearby resident female(s) have moved elsewhere. The male simply relocated itself to a taller bush next door.

Night walks have been unremarkable; surprisingly, the katydids seem very lethargic even in the darkest hours, although they do wave their antennae near-constantly once the sun sets. The deformed male often assumes an odd nighttime position in which it sits on a tall stem with head down and two front legs slightly in the air; perhaps this is a mate-searching behavior because scarabs have been known to use the same posture. I also did see a few small carabids (mostly Tanystoma maculicolle) and a pillbug with abnormally large yellow splotches, but the carabs failed to perform interesting behaviors.

No more coccinellid posts for a while; their aphids are all gone
