The abdomen is 10 segmented and the adeagus (the organ used to transfer sperm to the female) is on the 9th sternum.
The females, except in the Mengenillidae, are larviform (look like a larva) and lives entirely within the last larval skin within which she also pupated, inside the body of her host.
The eggs are retained within the body of the female and when they hatch the larvae emerge through the females genital tract and work their way out onto the body of the host, they are small active creatures with good legs and two long caudal setae.

Females answer several males in alternation and fail to respond to all male flashes, with the evident consequence that love knots frequently develop around such fickle females.
The ultimate consequence of these female behaviors is that "love knots" frequently develop around such fickle females and provide a potentially strong selective setting for competition to shape not only flash behavior itself, but perhaps morphological traits that affect the outcome of courtships.
Further, if the effective courtship arena for a female is no larger than a meter in circumference, as it is in P. pyralis, a larger lantern, with its greater output, is less of an advantage, even in protocols with long distance patrolling flights that rely solely on distanced, visual communication (Vencl and Carlson, 1998).

 Florida Entomologist, v. 84, n. 4, p. 565
Females of luminous cantharoid taxa, excluding Lampyridae, generally posses the same photic organ morphology as their larvae, which is generally paired, luminous spots on the post-lateral margins on some of the thoracic and each of the abdominal segments (Table 2).
Females, and males of the family Lampyridae vary in photic organ morphology (Lloyd 1978), perhaps due to sexual selection as the females of many firefly species attract mates via a luminescent sexual signal system (McDermott 1917; Schwalb 1960; Lloyd 1978 and 1979; Branham and Greenfield 1996;Vencl and Carlson 1998).
Rhagophthalmus ohbai females, in addition to retaining the larval pattern of photic organs, also possess a novel photic organ on the eighth ventrite, which is used in courtship, see Table 2 (Ohba et al.

Eoxenos is through the genital opening on the venter of the 7th abdominal segment, while in forms having apodous females the triungulinids at first pass through the genital ducts into the brood chamber and from there to the outside through the genital opening between the head and thorax.
Pupation.-- In species with apodous females, the individuals of this sex transform to the adult stage directly from the 7th instar larva without an intervening pupal stage.
Andrena, male or female, is not merely a diminished male or female; it is a female which takes on male attributes; a male that takes on the characters of the female."  This was later corroborated by other researchers.

 Arthropods of Economic Importance - Diaspididae of the World > Species: Family Diaspididae (Armoured scale insects)
Adult females are typical of the Coccoidea in being larviform, but can be distinguished from those of other families by: legs absent; antennae reduced to stumps, lacking articulation; abdominal segments IV-VIII fused into a sclerotized pygidium; and by secretion of a separate, non-living scale cover incorporating the shed cuticles (exuviae) of previous instars.
Protective scale covers are secreted by the immature stages of both sexes and the adult females, each successive stage enlarging and strengthening the cover made by the previous one, and incorporating the exuviae of the previous stage.
The general morphology of the adult female is discussed in the Introduction module.
