Diamondback Watersnake
Palo Alto, Clay Co., Mississippi
June 1, 1968

I caught this fairly large Diamondback Watersnake on the night of June 1, 1968 at a farm pond in n.e. Mississippi on the property of a cousin. We took the photos the next day. These are old slides, but the pattern of the snake is visible enough for an ID.

描述

This wasp is underwater searching for its host, Petrophila sp. caterpillars (also aquatic). I collected one of the wasps and sent it to Andrew Bennett at the Canadian National Collection of Insects. He identified it as Tanychela, and it would key to the species T. pilosa, but he thinks it could be a new species!

描述

This observation is for the prey animals found in an owl pellet I dissected. The date and location is accurate for where/when the pellet was found. I've left it at Vertebrata for now as it certainly contains more than one prey animal this time. The observation for the owl pellet/owl is here: https://www.inaturalist.org/observations/65913848

This pellet was huge! (last image) I found it in what seems to be two main pieces that were next to each other in the gravel. This one took much longer than the first pellet to go through and sort. It was also more difficult when it came to fully removing fur from the bones, so there are a few chunks that I simply couldn't clean off properly.

I've done my best to group most of the bones by what I think are related bones. Since this one had somewhere close to 280 different bones/bone fragments I didn't label them like the first pellet. Of course, I could be and most likely am incorrect about most of what they are so please correct me if you know.

Any help anyone can provide is greatly appreciated!

Water Temp. 28°C
Length: >800µm
Although from a different sample than the observation: https://www.inaturalist.org/observations/125250373, I think this is the same species. Here I was able to conclude that this individual has three toes. The sample was taken at the same location.
All images are of the same individual (and her daughter).

Night walk along bank of Grapevine Lake while waiting for insects to come to a couple sheets I had set up.

All of my blacklighting observations from my second night in Grapevine:
https://www.inaturalist.org/observations?d1=2022-07-20&d2=2022-07-21&nelat=32.9498178780538&nelng=-97.05853848413507&place_id=any&swlat=32.94857994678893&swlng=-97.06420867399255&user_id=joemdo&field:Light%20Source=395-400%20nm%20LED

Observed while visiting Grapevine for an education conference (SREB 2022). I was invited by the National Geographic education team to give a presentation on using iNaturalist in the classroom and had a great time presenting and also learning from the Nat Geo team.

I mostly stuck to the area near the Gaylord Texan hotel as there were plenty of woods to explore and blacklight at. I did also go on an iNat marathon on Friday the 22nd when I met sambiology and he took me to two really great spots: Cross Timbers Park and Tandy Hills.
I also went to LLELA shortly after to round off the day.

Here's a link to all of my Dallas/Fort Worth observations from this trip: https://www.inaturalist.org/observations?d1=2022-07-19&d2=2022-07-23&order_by=votes&place_id=any&user_id=joemdo

Rescued this Redhead today. It had a fishhook in its bill / face, and the fishing line it was attached to was frozen into the ice and the bird was trapped. Captured the bird, broke the fishing line, and then, with a friend, cut the fishhook in half and removed it from the duck's bill / face. It seemed vigorous and healthy. When we released it, it flew away strong and fast. Good deed done.

Extremely odd behavior from a Watersnake and Ribbonsnake... has anyone else observed something similar to this before? Both healthy adults with no visible injuries and both escaped rather quickly under their own power without coaxing.

I originally walked up on this pair around noon but the ribbon snake took off before I could get a picture of the odd behavior so I immediately left and came back about three hours later to find them both in the exact same position. So it’s fair to assume it’s a reoccurring arrangement between the two of them. The minimal research I have done has turned up nothing but I would love to hear from someone more knowledgeable about this sort of thing!

A life species for me! This little squirrel was digging seeds out of the snow under the bird feeder. I've thought we might have flying squirrels here because sometimes late at night, we hear the typical sounds of red or gray squirrels racing along the outside of our log cabin walls, but likely not either of those diurnal species.

Pseudoscorpion & its babies !
These tiny creatures are really amazing to watch. Other day I posted how these false scorpions carry their eggs, like a bunch of grapes on its back.
Here i got continuation of that , Where Mother pseudoscorpion is carrying its juvenile on dorsum of abdomen & few more are there on its ventral side.
I was not able to capture better than this as pseudoscorpions are restless creatures & they never sit when exposed to sunlight. They always move in search of the dark. These Arachnids have the unique strength of moving both forward & backward.
This makes us very difficult to capture . I am sharing three record photos,to showcase its maternal care.
ಹುಸಿಚೇಳಿನ ಬಗೆಗೆ ನಾನು ಈ ಹಿಂದೆ ನಿಮಗೆ ತಿಳಿಸಿದ್ದೇನೆ. ನಮ್ಮ ಜೇನು ಪೆಟ್ಟಿಗೆಯೊಳಗೆ , ಜೇನ್ನೊಣದ ಜೊತೆಗೆ ಇವು ಜೀವನ ನಡೆಸುತ್ತದೆ. ಪ್ರಕೃತಿಯಲ್ಲಿ ಇವು ಮರದ ತೊಗಟೆಯ ಅಡಿಯಲ್ಲಿ ವಾಸಿಸುತ್ತವೆಯಾದ್ದರಿಂದ ಇವು ಹೊರಜಗತ್ತಿಗೆ ಕಾಣುವುದೇ ಇಲ್ಲ.
ಈ ಅಷ್ಟಪದಿಯ ಅಧ್ಯಯನಕ್ಕೆ ಒಂದು ರೀತಿಯಲ್ಲಿ ನಮ್ಮ ಜೇನು ಪೆಟ್ಟಿಗೆಯೇ ಸೂಕ್ತ .
ತಿಂಗಳಿಗೊಮ್ಮೆ ನಾನು ನಮ್ಮ ತೋಟದಲ್ಲಿನ ಜೇನುಪೆಟ್ಟಿಗೆಯ ಕೆಲಸಕ್ಕೆ ಕೈ ಹಾಕಿದಾಗ ನನಗೆ ಈ ಹುಸಿಚೇಳುಗಳ ದರ್ಶನವಾಗುತ್ತದೆ.ಹಾಗಾಗಿ ಕ್ಯಾಮೆರಾ ಸದಾ ಜೊತೆಗಿರುತ್ತದೆ. ಇವು ಸದಾ ಕತ್ತಲಿನಲ್ಲಿ ಬದುಕುವ ಜೀವಿಗಳು. ಹಾಗಾಗಿ ನಾವು ಜೇನು ಪೆಟ್ಟಿಯನ್ನು ತೆಗೆದೊಡನೆ, ಪೆಟ್ಟಿಗೆಯಲ್ಲಿರುವ ಸೆರೆಗಳಿಗೆ ಹೋಗಿ ಅಡಗಿಬಿಡುತ್ತವೆ.
ಮೊನ್ನೆಯೂ ಹಾಗೆ ಆಯ್ತು.
ಜೇನು ಪೆಟ್ಟಿಗೆಯ ಒಳಗೆ ಹುಸಿಚೇಳೊಂದು ಈಗ ತಾನೇ ಮೊಟ್ಟೆಯಿಂದ ಹೊರ ಬಂದ ಮರಿಯನ್ನು ಬೆನ್ನ ಮೇಲೆ ಕುರಿಸಿಕೊಂಡಿತ್ತು. ಹೊಟ್ಟೆಯ ಕೆಳಗೆ, ದ್ರಾಕ್ಷಿ ಗೊಂಚಲಿನಂತೆ ಮೊಟ್ಟೆಗಳಿದ್ದವು ಮತ್ತು ಆ ಮೊಟ್ಟೆಗಳಿಂದ ಮರಿಗಳು ಹೊರಬರಲು ಆರಂಭಿಸಿದ್ದವು.
ಈ ಅಪರೂಪದ ಕ್ಷಣಗಳನ್ನು ದಾಖಲಿಸಲು ಅನೇಕ ಸವಾಲುಗಳು.
ಹುಸಿಚೇಳು ಕತ್ತಲೆಯನ್ನು ಹುಡಿಕಿಕೊಂಡು, ವೇಗವಾಗಿ ಚಲಿಸುತ್ತಿತ್ತು. ಇವುಗಳು ಹಿಂದೆ, ಮುಂದೆ ಅಡ್ಡಡ್ಡ ಚಲಿಸುವ ಸಾಮ್ರಾಥ್ಯ ಹೊಂದಿದೆ. ಹಾಗಾಗಿ ಇದನ್ನು ಫೋಕಸ್ಪೆ ಮಾಡುವುದು ಬಲು ಕಷ್ಟ. ಜೇನು ಪೆಟ್ಟಿಯೊಳಗಣ ಜೇನ್ನೊಣಗಳು ನನ್ನ ಸುತ್ತ ಹಾರುತ್ತಿದ್ದವು. ಯಾವಾಗ ಚುಚ್ಚುವುದೋ ಎಂಬ ಭಯ ಒಂದು ಕಡೆಯಾದರೆ, ಕಾಲಿಗೆ ಕುತ್ತುವ ಸೊಳ್ಳೆಗಳು ಮತ್ತು ಕಚ್ಚುವ ಕೆಂಜುಗಗಳು ಇನ್ನೊಂದುಕಡೆ .
ಇವೆಲ್ಲದರ ಮಧ್ಯೆ ನನಗೆ ಮೂರೇ ಮೂರೂ ಚಿತ್ರಗಳು ಸಿಕ್ಕವು. ಅಷ್ಟು ಹೊತ್ತಿಗೆ ಈ ಹುಸಿ ಚೇಳು ತನ್ನ ಮಕ್ಕಳೊಡನೆ ಪೆಟ್ಟಿಗೆಯ ಸೆರೆಯೊಳಗೆ ಅವಿತುಬಿಟ್ಟಿತ್ತು.
ಚಿತ್ರೀಕರಿಸಿದ ಆ ಮೂರೂ ಚಿತ್ರಗಳು ಇದೋ ಇಲ್ಲಿದೆ ನಿಮಗಾಗಿ.

6 - Floricane #1; retrorse prickles with broad bases, pubescent
7 - Floricane #1 close up
8 - Older floricanes (#2) bicolored; red on top, green on bottom
9 - Floricane #2; features consistent with floricane #1

15 - Dense leafy growth
16 - Terminal leaflet; shape: oval, base: rounded, margins: serrate, apex: caudate to attenuate; surface: not lustrous
17 - Abaxial leaf surface; petioles, petiolules, and primary veins armed; secondary veins and blade unarmed
18 - Petiole
19 - Terminal petiolule
20 - Primary and secondary veins
21 - Abaxial leaf blade white tomentose
22 - Stipules very long and narrow; Axillary bud present
23 - New leaves appear more corrugated and shinier than older leaves which are duller, less corrugated, and wider
24 - Several leaves with misshapen leaflets, or even a single oversized leaflet
GROWTH/HABIT
25 - New growth creeps along the edges, could be mistaken for vining/low habit
26 - 5 Leaflets on creeping floricanes more consistent than shrubby sections
27 - General growth habitat; between the bank of a creek and a concrete pathway; Full sun; This particular section was typically 4 ft high
28 - R. bifrons growing closest to path, with Cornus drummondii closest to the creek bank; Other nearby vegetation includes Celtis laevigata, Maclura pomifera, Salix nigra, Bothriochloa ischaemum var. songarica, Paspalum dilatatum, Calyptocarpus vialis
29 - Trying to estimate plant height using an isosceles right triangle based on the 6 foot wide path. Plants average 4-6 feet (12-18 dm)
30 - This particular colony of R. bifrons measured 166m along the edge
31 - Even when soil was scarce, the creeping canes would still spread thickly over the rocky ground.
32 - Soil along creek was clay over limestone
33 - USGS map indicates soil content: Thick clay units and thin limestone units alternating clay, marl, and limestone

Additional observations:

-- My first impression was this is the thickest growth, both in floricanes and leaf coverage, of any of the upright species. In heavy shade (under trees) the growth was not as thick or as tall. Probably the biggest colony of Rubus I've seen.
-- Several leaves had misshapen lateral leaflets, or a single leaflet, (1-)3-5 leaflets overall.

-- No prior season inflorescences seen at all. Nothing remaining on the stems or on the ground. (R. pascuus still has inflorescences attached at this time.)
