[6] Priocnemis conformis females predominantly prey on the early instars of mygalomorph spiders, including Stanwellia species, Cantuaria spp., and the black tunnelweb Porrhothele antipodiana.

[4] Nests of P. conformis females are typically closed and covered with leaves, twigs, berries, and soil (or sand in coastal areas).

The female may also make between three and nine additional burrows to act as a false nest, often arranged in an arc formation.

As a result of temporary paralysis, recovered spiders may spin a thick web matting on the cell floor.

[4] The robber fly Saropogon extenuatus acts as a mimic of female P. conformis, predating on males it attacks.
