On the other hand, the immatures that are destined to develop as males construct a loosely-woven silky filamentous cocoon after the second moult and undergo two moultings inside the cocoon with prepupal
and pupal stages, before emerging as winged adults (Dhawan et al., 2007; Vennila et al., 2010; Prasad et al., 2012; Fand et al., 2014).

The life cycle of the male includes 4 nymphal stages, of which the 3rd instar is considered the prepupal
stage and the 4th instar the pupal stage; followed by the fully developed adult (Borges da Silva et al.
Part VI: Descriptions of the fifth instar and prepupal
larval stages of Stethon pectorosus LeConte, 1866 (Coleoptera: Eucnemidae: Eucneminae: Mesogenini), with notes on their biology.
At the prepupal
stage, dry autoclaved sawdust was added to the Petri dish as a medium for pupation.
and planerocephalic stages of metamorphosis were recorded, and head eversion is the boundary between the two stages.
externa were maintained at 15, 20, 25 or 30[degrees]C under 70% relative humidity and 12 h photophase, and the duration of the embryonic stage, as well as the duration and viability of the larval (first, second and third instars), prepupal
, pupal and adult forms of the predator were evaluated.

At the end of the larval phase, the larvae have a quiescent prepupal
phase, which lasted about two days, and afterward they entered in the pupal stage.
After the fourth molt (males) or fifth molt (females), larvae drop to the soil and spin cocoons, enter prepupal
diapause (Knerer and Atwood, 1973), then pupate, and remain buried until autumn (McGregor and Sandin, 1968).
The DNA puff gene BhC4-1 of Bradysia higida is specifically transcribed early prepupal
salivary glands of Drosophila melanogaster.
