Nyctoporis adult dies, and other news

 Hisserdude reports that the N. carinata female I sent him a few months ago finally succumbed to age.


My own N. carinata larvae continue to occasionally surface and pace despite my providing of buried carrots. They seem not to like carrots. I guess I'll have to up the cornflake rations? I also recently cleaned their cage to remove mold. I found 21 N. larvae, zero springtails, zero mites, and zero sciarid maggots; evidently the microarthropods had all died and I won't have to worry about mite outbreaks.

Stenopelmatus gets thrown out

 

Not literally thrown, though. Its abdomen is very gelatinous and that would kill it.

Anyways, I took this pic and then released it in my front yard because it seemed stressed in captivity (it spent a worryingly large portion of its time in my cage aboveground, where it ran in panicked circles day and night). I assume the dirt in its cage was unsuitable for some reason. Fortunately it seems healthy now so it should likely survive in the urban wilds.


I was also wryly amused to find its missing sixth leg floating in the swimming pool today. For some reason insects occasionally lose limbs when drowning; perhaps surface tension twists the legs into unnatural postures and thus sprains enough muscles to amputate them.

I fed the leg to a captive hen. The hen was pleased.


EDIT: US Stenopelmatus are now all Ammopelmatus! Taxonomy sure changes fast!

I become an orthopteran hospital

Today I have acquired a Stenopelmatus specimen from my swimming pool! It has only five legs and seems somewhat unhealthy so I guess I am keeping it for a while. I released my Porcellio laevis male into the front yard to make room. The isopod was too secretive to be visible anyways, and invisible specimens always make me a bit nervous.


So far the cricket has chewed up an algal wafer and scattered crumbs everywhere. I will have to clean up the mess soon. It also vibrated, which means it is likely an adult (nymphs may sometimes vibrate too).

More significant annoyances

 The Physciella samples were once again ruined, though through no fault of my own. Why are physics and society hellbent on killing me to death?

Also, two days ago I noticed a Nyctoporis carinata larva running in circles around the surface, and it was emaciated-looking (I have also seen multiple thin but non-surfacing larvae in the distant past and amped up the cornflake rations in hopes of fattening them; they didn't help, and were not eaten very much). The surfaced larva made some efforts to chew a cabbage leaf and then reburrowed after a number of minutes of gnawing. I strongly suspect that nyctopores, unlike many commonly kept Tenebrionidae, have larvae that are so timid that they do not usually surface for food unless starving. And since the garden soil my larvae are in is not very nutritious, presumably they could not gain adequate nutrition when away from the surface. I buried a mushroom stem in the dirt in hopes of increasing their food intake and will add some underground carrots later.

I obtain one (1) isopod

 A few nights ago I was doing laundry and saw a very large (larger than 1cm) isopod running across my garage! Upon closer inspection it was neither the ubiquitous Armadillidium nor the (less common but hyperabundant in some microhabitats) pruinose Porcellionides. I strongly suspect it is a male Porcellio laevis specimen but have not bothered to identify it yet. Update: it is indeed a male laevis!


I lost my phone again, so photos coming later.

I swear I'm not dead ye- oh wait

News: the inchworm depupated successfully on Nov. 6! It was Chrysodeixis includens. I dumped the moth on someone's Lantana bush shortly after it molted. Interestingly it was prettier than I thought it would be; I didn't realize it was reflective like bronze/silver satin; the sheen is less apparent in photos. I think I did a somewhat good job of capturing the pleasant coloration here though.


The Nyctoporis carinata female adult I sent Hisserdude has recovered from shipping stress and is still alive in a box somewhere in his house. The larvae at my house are doing well in garden soil and eating assorted vegetables happily. They are now large enough to photograph! Some individuals have very dark brown anteriors and others of the same size have pale orange anteriors but all of them are creamy white and puffy on the rest of their body. They also have sparse hair bristles over their bodies but this isn't visible here. Here is a pic, interestingly it is currently the only online photo of one in existence:


They are slower at walking than both Tenebrio and Zophobas and regularly engage in peristaltic contractions when locomoting (T and Z larvae only seem to peristalse when being grabbed or in tight spaces). They also flop with extreme violence if dug up, much more so than T/Z; however once finished flopping they stop moving for a while. They will make no attempt to rebury themselves for several minutes unless the substrate is vibrating, just like some dung scarabs. If the vibration stops they immediately freeze again. Of course once the several minutes have passed they will dig, vibrations or no vibrations. They cannot dig quickly if dug up, but oddly if feeding on vegetables with only their heads sticking out they can retract just as quickly as Z/T can when frightened.



Unfortunately the Cotinis mutabilis both died during shipping.

Nyctoporis arrives!

Hisserdude has successfully acquired my specimen, here are some pretty macro shots he took of it!

An inchworm pupates at me

prepupal larva in finished cocoon


Found this noctuid on my floor on Oct. 24, it ate a tomato leaf that night and started producing a cocoon the next morning. Currently it is a bright green pupa.

larva several hours before cocoon construction

Several bugs vanish from my inventory

Manduca sexta died several days ago. In life it kept drooling and getting leaf sludge on its face/legs when eating, and like a starving mealworm it was suspiciously shortbodied. These are highly unusual symptoms of disease, normally infected specimens begin flopping about uncoordinatedly and vomiting; mine did not show any obvious signs of distress. A few days before it died it lost most of its appetite (it did still eat hours before perishing though) and just stopped moving and eventually turned limp, but without rotting or liquefying. Also unusual. Pretty sure it caught a pathogen in the wild, because it was already short and stout when I first laid my eyes upon it.


The Nyctoporis carinata female was sent to Hisserdude. He should prolly write a blog post soon if it makes it to his house alive.


I'm also currently mailing out my male Cotinis duo.



The only specimens I currently have left are the Nyctoporis larvae, which unlike the adult are too small to be mailed.
