Interesting video of some thin banded bees in this buckfast colony:
Sorry, I have no ability to distinguish the Tunisians.Would you be interested in analyzing for Tunisian bees? Right now most of our colonies are showing Tunisian bee traits (only 8-12 colonies left, but am multiplying now).
The "Third" strain is too similar to the "First" strain in looks. So I was most likely wrong. It is a mystery why some colonies are sluggish in Spring build-up. It seems as if it is related to these Tunisian like colonies though. Also, it is only the two or more story colonies that have had this problem of breeding only drones in the Spring, and not workers. When they do this it doesn't help with Varroa. Replacing the queen fixes the problem I have noticed.Now I am thinking there could be a few different strains of Tunisian bees here in our colonies in North Carolina... I used to think that possibly it was hybridization that caused some of the variations in some Tunisian like colonies we had in the past.
Here are some videos of Tunisian like bee in our colonies (some of these videos I have already posted here on this topic, but I am organizing them to strain of Tunisian the best I can tell):
Colony #1Colony #2(?) Colony #3
Colony #1 Light colored bees August 2020
Colony #2 Tellian bees? North Carolina April 10th?
Colony #3 Thin banded strange bees
Third (Really a different strain or the same as or hybrid of First?)
These are almost as if they are slightly hybridized with German black because they could be all black, and might have slightly wide abdomen and solid colored, compared to the first translucent strain posted above. These might be what I have been thinking were Spanish black bees in this post:
Sluggish build-up in Spring, but produce drones at the usual time as other colonies, so proportionately more drones than workers in early Spring. Propolizes a lot and are aggressive.
Colony #1 Honeybee colony August
(?) Colony #2 2020 February 24th #9
Colony #3 March 5th? 2021 bees
Colony #4 2020 February 25th Dark bees (Carniolan?) #2
Bear in mind that most of this I am uncertain of and I am doing a lot of guessing.
An interesting light colored colony that looked somewhat Tunisian. Hybridization caused light coloration?
This video is sort of what I have been thinking were the Spanish black bees with the smaller abdomens than German black bees:
And this I took recently:Looking for Spanish black bee traits. Possibility of a thick banded strain of Spanish black bee?www.youtube.com
This colony we have here in North Carolina has lighter bees with thick bands:(sorry for bad, shaky video!)
I am wondering whether it is possible that these have Saharan bee (Apis mellifera sahariensis) genetics in them because of the lighter color, and because I have read from here (https://www.tandfonline.com/doi/full/10.1080/23802359.2017.1365647) that Saharan bees live in areas where the temperature can get cold:
"It has the ability to adapt to extreme conditions like temperatures in Saharan zones ranging from −10 °C to over 50 °C to drought conditions (Adjlane et al. 2016) and high altitudes (Haccour 1960)."
Light colored, thin banded Saharan bee video on YouTube to compare:

I still doubt that we have Saharan bees here in North Carolina because we have a humid climate, while the Saharan desert is very dry.
We still do get a little heat or dry dormancy during our summer, which you can see in these Tulip poplars loosing leaves in July 25th 2020:

Russ, how did you get the ABJ articles online? I would like to link online photos of interesting bees that I see in the ABJ magazine.Nathaniel:
Good article in the April 2021 ABJ (attached)- thought it might be interesting to you.
The article you showed me before says that Spaniards brought bees to Florida, but if the Spaniards had brought them earlier than the German black bee, then the honeybee should have been found already in America when the colonists came.Nathaniel:
I have enjoyed reading this thread. You may have already had the opportunity to read this series of articles written by Dr. Everett Oertel, USDA Research Entomologist published in circular in the American Bee Journal c. 1976, but if not they are well worth the read. It is the most comprehensive and well-researched summary on the topic I have found, at least without the benefit of background genetic testing.
A summary of this information was also included (attached) in a 1980 USDA publication.
Have a great weekend.
Nathaniel:Russ, how did you get the ABJ articles online? I would like to link online photos of interesting bees that I see in the ABJ magazine.
Okay, thank you. I looked at the ABJ website and found out that the older magazines are free to look at online:Nathaniel:
I take the digital subscription of ABJ. For only $16 a year, the information contained within is well worth it.
When you subscribe, you receive a monthly link to the latest edition which allows you to read it online, download it as a PDF and search back copies (among other things).
Sorry to read this, Joe. Surely there has to be more of this genetic strain in your flight path and maybe you can luck-into some in a swarm trap here soon.Update: The tree hive of black bees near me didn't make it this winter.
There's no hair between tergites to speak of, except one vareity that consistently has hair between 2 tergites (can't remember which) near the end of the abdomen. There were several on my feeder yesterday so either:Sorry to read this, Joe. Surely there has to be more of this genetic strain in your flight path and maybe you can luck-into some in a swarm trap here soon.
Do the black bees around you look more AMM or Carnica-type? I do get a lot of dark bees in my colonies with narrow light-colored banding at tergites, but morphologically they are not blunt in the abdomen like the photos I see of true AMM- makes me think there likely is some dark bee influence in there but a whole lot of ligustica and carnica too.
Joe:We also still have the feral bees that have one band of black high on the abdomen then shiny jet black as if you dipped their little butts in paint.
Now that is a black bee- I've never seen one so dark and devoid of any variation in color. If I didn't know better, I would wonder if that bee is suffering from CBPV:Russ, I caught a pic of one today. This one has been into a bit of sugar-water, but you get the idea.
They have some caramel in the upper abdomen once full. Someone else mentioned disease a while back as a possible cause but didn't have details. I can't say for sure, but I can say there were as many as 10 working an outdoor feeder at any given time today. I'll have to say the "Window Bee" pic looks cloudy across the thorax. These don't have that. They have quite a bit of short hair, the one in the pic has been swimming in sugar water.Now that is a black bee- I've never seen one so dark and devoid of any variation in color.
