I caught 3 lasius minutus queens in September last year hibernating under a large stone. I gave them lasius pallitarsis hosts and all 3 survived hibernation and have their first clutch of eggs. These queens are absolutely tiny, half the size of an aphidicola queen and very slim. This journal will be documenting their progress as they raise up their first workers, and hopefully the growth of the colonies.

How are these doing?


Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

i put them back into hibernation because they stopped laying and ate their eggs, presumably from lack of hosts. Hosts were also slowly dying. I’ll take them out again in spring.

Update?

one is left. She was woken up a few days ago, but only has a single host. I'm giving her more callows now, and plan to boost with pupae soon.

A lot has happened since i last updated this journal. The one queen now has around 100 hosts and is quite physogastric, with tons of eggs, larvae and a few pupae. The original plan was to update this journal in a few weeks when the first biological worker emerges, but here is another update in the meantime.

(Note that these images were taken months ago when the queen just started getting physogastric and laying eggs, so all those pupae and callows aren’t hers)

These guys got their first biological workers a few months ago, and are now back in hibernation.

This is the first time I've actually seen a physogastric parasitic Lasius queen.  Glad to see your parasitics are doing well!

Parasitic Lasius are actually physogastric more common than non-parasitic Lasius in the early stages, since they lay wholesale batches of eggs all at once and grow a ton faster than their non-parasitic counterparts.

In hibernation right now but I'm not sure if this colony is gonna make it. After getting biological workers they sorta began fizzling out for some reason.

Impossible considering the time of year and lack of host colonies in my collection. My plan is to keep her hibernated until springtime when i can get pupae.

I experienced the same with my parasitic Lasius (they then proceeded to die), my guess is that in the normal colonies they invade they are boosted by the remaining host brood in the nest, and this may aid in success for some species.

Yes, Lasius Subumbratus do this a lot in the wild.
