Large colony under a rock.

Formiga pequena, uma das menores do genero. pouquissimo coletada, encontrada em amostra de serrpilheira, ampliando a área de ocorrência da mesma.

I was stunned to see a complete demon like face on this bug..!!
To me this face is complete with the beautiful crown formed by the limbs... :-)

size: 1cm approx

This observation is for the larger insect in this photo.

The pugnacious ants were bullying Tetramorium. They would pick them up and drop them, but I didn't observe any killing.

None

2.5mm body length. In moist leaf litter next to log. Active. Air temperature about 56°F

overachieving tents of L. hayashi. Thick enough for me to break and see the cross section without crumbling the whole. Seen people mistaken these as works of termites

my favorite find of this years trip!
