Step-by-step solution for: Insects Dichotomous Key | MadeleineHaddad | Live
To solve this, we will go through each picture one by one and follow the "Dichotous Key" steps. A dichotomous key is like a choose-your-own-adventure game where you answer questions to find the right name.
Here is the step-by-step identification for each animal in the pictures:
Top Row (Left to Right):
1. First Picture (Spider with long legs):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2b: 8 legs $\rightarrow$ Go to 5
* Step 5b: Light hair covering the body $\rightarrow$ Go to 6
* Step 6b: Often brown body and makes funnel webs $\rightarrow$ Hobo Spider
2. Second Picture (Moth):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4c: Front Wings are hidden with wing casing? No. Let's look closer. It has colored wings. Wait, let's re-read step 4.
* Actually, let's look at Step 8 first because it mentions antennae. But we have to follow the numbers.
* Step 4a: Colored Wings $\rightarrow$ Go to 8
* Step 8b: Antenna are feathery with no club at the end $\rightarrow$ Moth
3. Third Picture (Ant):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3b: No Wings $\rightarrow$ Go to 7
* Step 7b: No Jumping $\rightarrow$ Ants
4. Fourth Picture (Wasp):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4b: Transparent Wings $\rightarrow$ Go to 9
* Step 9b: Two sets of transparent wings $\rightarrow$ Go to 10
* Step 10b: Few hairs, longer body $\rightarrow$ Wasp
5. Fifth Picture (Hairy Spider):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2b: 8 legs $\rightarrow$ Go to 5
* Step 5a: Very Hairy Body $\rightarrow$ Tarantula
6. Sixth Picture (Snake):
* Step 1a: Vertebrate (has backbone) $\rightarrow$ Rattlesnake
***
Bottom Row (Left to Right):
7. Seventh Picture (Fly):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4b: Transparent Wings $\rightarrow$ Go to 9
* Step 9a: One set of transparent wings $\rightarrow$ Housefly
8. Eighth Picture (Bee):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4b: Transparent Wings $\rightarrow$ Go to 9
* Step 9b: Two sets of transparent wings $\rightarrow$ Go to 10
* Step 10a: Hairy, wide body $\rightarrow$ Bee
9. Ninth Picture (Butterfly):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4a: Colored Wings $\rightarrow$ Go to 8
* Step 8a: Antenna are club-shaped with a bulb at the end $\rightarrow$ Butterfly
10. Tenth Picture (Spider with red hourglass):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2b: 8 legs $\rightarrow$ Go to 5
* Step 5b: Light hair covering the body $\rightarrow$ Go to 6
* Step 6a: Black with large red symbols on body $\rightarrow$ Black Widow Spider
11. Eleventh Picture (Grasshopper):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3b: No Wings (Note: Grasshoppers have wings, but in this specific key, "No Wings" leads to step 7 which distinguishes jumpers. Let's trace carefully. If we chose "Wings" at step 3, we go to 4. Grasshoppers don't fit well into 4, 8, 9, or 10. Let's look at Step 7. Step 7 comes from "No Wings". This implies the key classifies the grasshopper here based on leg type rather than wings, or assumes the wings are folded/hidden. Let's follow the "Jumping hind legs" clue).
* Step 3b: No Wings $\rightarrow$ Go to 7
* Step 7a: Jumping hind legs $\rightarrow$ Grasshopper
12. Twelfth Picture (Beetle):
* Step 1b: Invertebrate $\rightarrow$ Go to 2
* Step 2a: 6 legs $\rightarrow$ Go to 3
* Step 3a: Wings $\rightarrow$ Go to 4
* Step 4c: Front Wings are hidden with wing casing $\rightarrow$ Beetle
Final Answer:
Top Row:
1. Hobo Spider
2. Moth
3. Ants
4. Wasp
5. Tarantula
6. Rattlesnake
Bottom Row:
7. Housefly
8. Bee
9. Butterfly
10. Black Widow Spider
11. Grasshopper
12. Beetle
