Fig. 2. Camera lucida drawings of the flexor tibiae muscle in the metathoracic leg
in the locust Locusta migratoria (A) and the cricket Gryllus
bimaculatus (B). The relative size of the accessory flexor muscle (red)
against the main flexor muscle (orange) in the cricket is larger than that in
the locust. Whereas the locust has a thin flexor apodeme in the distal femur,
the cricket has a cushion enlargement on which the accessory flexor muscle
attaches.
