Identify the correct combinations.
(a) Housefly-labellum-pseudotrachea
(b) Moth-labellum-Dutton's membrane
(c) Butterfly-first maxillae-galea
(d) Tsetse fly-rostrum-haustellum
Identify the correct combinations.
(a) Housefly-labellum-pseudotrachea
(b) Moth-labellum-Dutton's membrane
(c) Butterfly-first maxillae-galea
(d) Tsetse fly-rostrum-haustellum
The correct option is B a and c
(a) Flies with fused labella have
food channels in the surface of the labella. These are called pseudotracheae.
(b) Dutton describes a fine
membrane covering in the area between mosquito extended tongue and the base of
the labellae.
(c) Butterflies
have mouth parts specialized for probing into a flower and sucking out nectar.
A long, slender proboscis is formed by the two galea of
the maxillae which interlock to enclose a central food canal.
(d) In
Tse-Tse fly, a pair of maxillary
palps help to protect the more delicate proboscis or haustellum which lies
between them when it is not in use.
So, the correct answer is 'a
and c'.
