Ceropales pacifica
Townes, 1957
Ceropales pacifica is a spider wasp ( Pompilidae) described by Townes in 1957. In Colorado Springs, it has been observed as a potential model for Müllerian or , with the ichneumon Ceratogastra ornata showing striking similarities in coloration and pattern. As a member of the Ceropales, it belongs to a group of spider wasps known for their distinctive and .

Identification
Spider wasps in the Ceropales can be distinguished from similar ichneumon wasps by their : Ceropales has fewer, longer antennal segments compared to the many short segments of ichneumon wasps. Wing venation also differs, though this requires close examination. Ceropales are slightly larger than the 10-12 mm body length typical of Ceratogastra ornata.
Distribution
Known from Colorado Springs, Colorado, USA based on field observations. The specific epithet 'pacifica' suggests a broader western North American distribution, though precise range boundaries require additional documentation.
Ecological Role
Has been proposed as a visual mimicry model for the ichneumon Ceratogastra ornata, suggesting potential involvement in Müllerian or complexes.
