Dipogon
spider wasps
Dipogon is a genus of small spider wasps (Pompilidae) characterized by ant-mimicking dark-banded wings and a distinctive 'beard' of hairs on the maxillary palps used to transport nesting materials. These solitary wasps are primarily forest-dwelling, hunting spiders on tree trunks and constructing multi-celled nests in pre-existing tubular cavities such as beetle tunnels or hollow plant stems. The genus exhibits notable behavioral plasticity in nest construction, using mud, leaf fragments, insect parts, and even stolen bee provisions to form cell partitions.
