And, some more myrmecophiles from Sat.

Camponotus were preparing for colonial proliferation.

Reproductives patiently wait for the right moment.

Some case-bearing leaf beetles can be found with ants, where they feed on nest refuse. I’ve previously collected adults and larvae from Arizona, Arkansas and Oregon. The ones from Arizona and Oregon were in the genus Saxinis.

I kept them alive. We'll have wait and see what the adults look like.

Poster child myrmecophile, Myrmecophilus, hey it’s right in the name!

An immature female, you can see her still-developing ovipositor.

The current revision that treats North American taxa, in my opinion, is not that reliable. I don’t think hind leg spine number is a stable enough character to be used in identification. I have seen taxa with unequal numbers between their hind legs. I think molecular data will give us an entirely new perspective, just as the research in Japan has. I suspect this is what people call Myrmecophilus pergandei.

There is some evidence to suggest that individuals develop according to the size of their hosts. Therefore, some species are known to demonstrate extreme size polymorphism. Could this really be the reason behind these observations?
