Passaloecus sp


Female: 5.0-6.0 mm, glabrous, anterior side of scape and mandible yellowish white.


The cell partitions are built out of conifer resin. The females can bore the galleries themselves or use existing ones left by xylophagous organisms (Coleoptera or other Pemphredoninae). The species is caulicolous: nests are excavated in stems with dry pith (Rubus, Sambucus, Lonicera, Hedera, tree trunks) or made in existing galleries left by xylophagous species.
