1. 0:01spring is in full force right now with
2. 0:03more sunlight and higher temperatures
3. 0:05the plants are growing again and turn
4. 0:06nature into a symphony of green and all
5. 0:09kinds of other colors but not only
6. 0:11plants come to life there are also
7. 0:13countless types of insects roaming and
8. 0:15buzzing around again some are super
9. 0:16important some are super annoying and
10. 0:18some deserved the description creepy
11. 0:20crawly but although they sometimes
12. 0:22appear to be very different and distinct
13. 0:24generally with a few exceptions all
14. 0:27insects have the same basic anatomy this
15. 0:29is due to the fact that they are all
16. 0:31related and share a common ancestor at
17. 0:33the base of their family tree
18. 0:35to get a better understanding of all
19. 0:37bugs and beetles around you we will try
20. 0:39to bring you the basic anatomy of
21. 0:40insects in an easy explanation
22. 0:49[Music]
23. 0:52in the adult stage of life all insects
24. 0:54have three distinct body parts which are
25. 0:56actually somewhat similar to the human
26. 0:58body parts there is a head a thorax and
27. 1:01an abdomen but let's first take a closer
28. 1:02look at the head
29. 1:04the head obviously contains a pair of
30. 1:06compound eyes and also a mouth part and
31. 1:08a pair of antenna especially the mouth
32. 1:10part comes in many different sizes and
33. 1:12appearances which are mainly adapted to
34. 1:14the diet of the insect
35. 1:16if the animal feeds on solid foods the
36. 1:18mouth part is usually a combination of
37. 1:21biting and chewing pieces like the ones
38. 1:23from grasshoppers or beetles
39. 1:25other insects like the mosquito or fleas
40. 1:27have a proboscis which is used for
41. 1:29piercing and sucking
42. 1:30similar to the proboscis of a mosquito
43. 1:33are the ones of butterflies and moths
44. 1:35however those are usually long and
45. 1:37tube-like and can be uncoiled to scythe
46. 1:39nectar outer flower nectaries instead of
47. 1:42piercing skin or plants therefore this
48. 1:44mouth part is referred to as a siphoning
49. 1:46mouthpart
50. 1:48insects like flies on the other hand
51. 1:49have a sponge-like mouthpart this is
52. 1:51used to pump saliva onto the food sewers
53. 1:54to dissolve it and to suck it up again
54. 1:57now let's move over to the thorax which
55. 1:59mainly has a task to hold appendages
56. 2:01used for movement the thorax can be
57. 2:03divided into three subparts called the
58. 2:05prothorax mesothorax and metathorax each
59. 2:09of those three subparts hold one pair of
60. 2:11legs which are then called fore mid and
61. 2:14hind legs
62. 2:15just like the mouth part the legs can be
63. 2:17heavily modified depending on the need
64. 2:19of the insect they are obviously there
65. 2:21for locomotion like running and jumping
66. 2:23but also for things like digging holding
67. 2:26prey or grabbing onto a mating partner
68. 2:28insect legs might look very different
69. 2:30but thankfully all of them follow the
70. 2:32same basic principle and are divided
71. 2:34into five main parts the coxsa
72. 2:37trochanter
73. 2:38femur tibia and tarzas
74. 2:43also attached to the thorax are the
75. 2:44wings which usually come in two pairs a
76. 2:47big exception to that is the common
77. 2:49housefly which has only one pair of
78. 2:51wings however they do have something
79. 2:53called halters which is an evolution of
80. 2:55the second wing pair the halters are
81. 2:56flapped at a high speed and are
82. 2:58therefore maintaining balance in the air
83. 3:00while doing complicated flight movements
84. 3:02such as tight spirals or zigzags but
85. 3:04like i said before most other insects
86. 3:06have two pair of wings one pair of wings
87. 3:08is essentially made up of a thin
88. 3:10membrane which is supported by veins
89. 3:12around the edges and within the membrane
90. 3:14in some insects like bees the second
91. 3:16pair of wings is also made up out of
92. 3:18this thin membrane but there are other
93. 3:20insects like beetles which have a harder
94. 3:22outer wing called elytra the elytra
95. 3:25covers and protects the underlying
96. 3:27membranous wing and is not necessarily
97. 3:29used for flight
98. 3:32like we mentioned at the beginning the
99. 3:33last body part of an insect is the
100. 3:35abdomen which mainly contains organs
101. 3:37like the heart a huge part of the
102. 3:39digestive system and parts of the
103. 3:41reproduction organs it may also contain
104. 3:43external structures like a stinger a
105. 3:45good example for that are wasps and bees
106. 3:48in worker bees its main purpose is
107. 3:50self-defense however in queen bees the
108. 3:53stinger is also used for laying eggs so
109. 3:55it plays a vital role in reproduction
110. 3:57and survival of the species i really
111. 4:00hope this video helped you to get a
112. 4:02better understanding of every part of an
113. 4:03insect and what it is responsible for
114. 4:06keep in mind that we mainly covered
115. 4:07basic information and that there is a
116. 4:09lot more detail to discover if you are
117. 4:11interested check out the sources in the
118. 4:13description box below we also created a
119. 4:15similar video for the anatomy of a tree
