Summary of discussion quoted by @saswathy679

30th August 2021 - CUBE Chatshaala Discussion - White Boards :point_down:
Discussed about model systems : Fruit Fly, Mosquito, Ants (Insects).
:black_small_square:Where can we find Fruit Flies?:thinking:

:black_small_square:How Fruit flies Look Like? Is it easy to distinguish from other insects?:thinking:

:black_small_square:What are the characteristics features that very well visible in fruit flies? Which part of the body well visible like… Wings, Eyes, Abdomen…? What is the actual size of this small flies?
:black_small_square:What are similarities & Dissimilarities between Fruit flies and Mosquitoes?

Fruit Flies and Mosquitoes, both of them are belonging to;

:black_small_square:Kingdom : Animalia

:black_small_square:Phylum : Arthropoda (Because both of them have joined appendages)

:black_small_square:Class : Insecta (Body divided in to 3 parts Head, Thorax abdomen. Have 3 pair of legs & 1 pair of antenna, also have compound eyes.)

:black_small_square:Order : Diptera
Both have 2 wing (one pair of wing)

Coming in to Family level Fruit Files are belonging to Drosophildae, Mosquitoes are belonging in to Culicidae.
One interesting point added by @Navaneel that insects have fore wing & hind wings. Only Fore wing is Expressed. Hind wing converted in to halteres in the case of Dipterans.

Flies are insects of the order Diptera, the name being derived from the Greek δι- di- “two”, and πτερόν pteron “wing”. Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. https://en.wikipedia.org/wiki/Fly

Reference given by @Yash :point_up_2:

:black_small_square:But did other insects have halteres first?

:black_small_square:Are there examples of insects having just halters…?

It is generally accepted that the halteres evolved from the non-flight wings of insects — the hind-wings of Diptera and the fore wings of Strepsiptera respectively.
