Dipogon geronimo

Evans, 1974

Dipogon geronimo is a of spider wasp ( Pompilidae) described by Evans in 1974. The Dipogon comprises small, -mimicking that hunt spiders on tree trunks. Members of this genus are rarely observed due to their effective ant mimicry, small size, and forest-dwelling habits. Females provision nest with paralyzed or killed spiders, constructing unique nest partitions from mud mixed with organic debris.

Habitat

Forest edges and wooded areas; hunt on tree trunks and among foliage.

Distribution

Eastern North America; specific range details for this are not well documented. The related species Dipogon calipterus calipterus ranges from Massachusetts to North Carolina, Indiana, and Illinois.

Diet

Spiders, particularly crab spiders ( Thomisidae, especially Xysticus), jumping spiders (Salticidae), and ground spiders (Gnaphosidae).

Life Cycle

Females construct nests in pre-existing tubular cavities such as abandoned tunnels of wood-boring beetles or soft pith in dead plant stems. Nests contain linear series of separated by partitions constructed from mud mixed with leaves, insect body parts, or caterpillar . Each cell is provisioned with one or more paralyzed spiders and sealed with an laid upon the prey.

Behavior

-mimicking appearance and movement; slow, deliberate locomotion on tree trunks. Females sometimes kill prey specifically for self-feeding rather than solely for offspring provisioning—a relatively unusual among spider wasps.

Ecological Role

of spiders; contributes to regulation of spider in forest .
