|
wing disc
|
Dorsal imaginal disc of the mesothorax. Precursor of dorsal mesothoracic structures of the adult including the postnotum, scutum, scutellum, wing, wing hinge and part of the notal plura. |
|
FBbt:00001761
|
imaginal disc
|
A sac shaped epithelial structure in the larva that gives rise to part of the adult integumentary system. One side of the sac consists of peripodial epithelium, the other of columnar epithelium. A single anterior-posterior compartment boundary bisects both peripodial membrane and columnar epithelium. Cells do not cross this boundary during growth and development of the disc. |

|
thorax
|
The main middle section of the insect body comprising three thoracic rings: the pro-, the meso- and the metathoraces which are more or less well fused and cask-like sometimes having on the upper lateral part one of two pairs of wings, while on the ventrolateral part each thoracic ring bears a pair of legs. |

larva

|
|

|
pupa
|
The pupa is the name given to the organism at the period of the life cycle that begins once larval/pupal apolysis is complete, as indicated by the expulsion of the larval armature. Early in this stage the legs and wings reach full extension along the abdomen. The stage ends when the pupal cuticle separates from the underlying epidermis (pupal/adult apolysis), and the eye cup becomes yellow at its periphery. The duration of this stage is approximately 32 hours at 25 degrees C, and spans from 132.2-164.3 hours after egg laying, or is the period of 12.2-44.3 hours after puparium formation. |

|
mesothoracic segment
|

|

|
prepupa
|
The prepupa is the name given to the organism at the period of the life cycle that begins at puparium formation and ends when larval/pupal apolysis is complete, as indicated by the completion of imaginal head sac eversion and the expulsion of the oral armature of the larva. Duration at 25 degrees C is approximately 12 hours. It occurs 120-132.2 hours after egg laying, and is the period of 0-12.2 hours after puparium formation. |
