| Modern female wasps having other than six abdominal segments I

| fertilized or "foundress" females do share with males the need
| for extra body space to support functioning and thus unusually
| large reproductive organs, females specialized for the
| reproductive role display morphological differences beginning
| from larvahood to accommodate the task. (In eusocial species,
| reproductive females or 'gynes' differ from workers or 'ergates'
| in having the ability to be inseminated; in subsocial species,
| gynes are raised and fed for the role from birth and as a result
| simply grow up extra big and strong, with noticeably larger
| abdomens in body proportion than their sisters whose labor is
| less deferred.)
|
| _edit:_ Fixed a bug resulting from a Wikipedia editor doing a
| lousy job with taxonomy. It is actually possible that some lineal
| relationship exists between structures described here and those
| of modern male wasps with a seventh gastral segment.
