I decided to publish and continue my Lasius flavus journal here. Also, I am going to update it at least every week from now.

 

 

Lasius flavus journal.

Year 2015

 

30 May

I went out in the afternoon. Dug up a few parches of thick moss (where a dirt pile was) with hands and surprisingly (no nuptial flights seen) managed to catch two young Lasius Flavus queens(~7mm). Filled up half of  the glass basin(10x15x10) with their natural soil, which I gathered near. Put some clay (pebble-like) in the corners, all the way from the bottom till the top (approx. 1-2cm diameter). And then filled 0.5 cm on top with dry sand-loam. Then put 3 dark-colored pebbles in the corner and put two queens in, which seemed energetic and healthy. They wandered around for about 10 minutes till both started founding their colony together under those three pebbles. After a while they dug out a chamber or two near the glass wall. I put some type of paper to cover it from light. Seems that I have a polygyne colony starting here.

 

31 May

I keep them in a room temperature, which is about +23.5Celsius. The other queen seems to have moved a bit more towards the center of the basin. Only one queen is visible near the glass, but still not that clear as yesterday. I hope to see some eggs in the near future, in about a week or so, but theese species are known to have really small eggs and larvae, as they are small anyway. Poured a drop of water or two on the clay, should be enough for a month, because humidity now is about 85%. No water seems to condensate on the walls and there is a ventilation provided with a mesh in the middle of the lid.

 

7 June

I don’t see any of my two queens. Soil seems to be dug differently though. No mold in the basin, some plants started to grow, for instance, 1cm of moss in the corner.

 

1 September

I had to clean the formicarium because I thought that there is some sort of fungus growing near the glass and when I slowly removed all the dirt it was clear that one queen has died(or eaten, I can’t find her), but the other queen has her first small worker(~2mm) and there is one more pupae and some eggs.

Moved them to a small container. Put some sugar-water in there.

 

7 September

Container room temp. ~+22Celsius, Humidity 70%. Offered them small spider, which has been in freezer for a day.

 

8 September

I don’t think they have touched spider, but they might have in the night. Removed it anyway, I don’t want any unwanted „guests” in my formicarium.

 

14 September

The colony has moved to a plastic tube. Gave them 1 spider and a piece of pollen. Also, I offered them a bit of honey a few days ago, seems that they have tried it, but now as they moved to their tube, I removed and cleaned arena, which was their emergency home. The queen is 8mm and the nanitic is 3mm (measured with a ruler).

UPDATE 24th September

 

The young colony of Lasius flavus is doing quite well, I hope that they have touched any bug I gave them or at least some honey. The first worker seems to be trying to cut out the second worker from its cocoon(I think so and I am going to update after ~7 hours). Also, they have about 4-5 eggs now, but I can't really tell, because they are on/ near the cotton.

Nice young colony.

Did you cut up the spider, or poke a needle through it?  I find young Lasius colonies have problems with whole prey.

 

Mine always loved spiders, mealworms, crickets, sugar water, and especially fruit flies (or similar sized flies).

Yes, I did cut up the spider after removing it from the freezer.

Also, the new worker has been cut out of its pupa and it seems to be alright, it has yet to darken in color though. The worker has light yellowish color and it is about the same size as the first worker.

UPDATE 5th October

 

The colony is doing well, they have a bunch of eggs. I have been feeding them with some honey, now a slice of apple is in the tube.

Just two, I hope there will be more after hibernation.
