Larvae Observations in-class activity

- color: creamy white body with a black thin tail that is about 3/4 of an inch long, longer than the body itself
- moves around like a small caterpillar with tiny little legs, however its tail is stiff
- appears that its larva body is inside some sort of transulcent cacoon
- outer surface is somewhat sticky to small particles, but otherwise it is easy to roll over
- white insides
- some sort of hole in the darker mouth region that pokes out before every time it moves forward
- appears to have a difficult time climbing up and out, probably due to its tail
- crawling alongside the outer edges, outer surface is ridged
- symmetrical, bilaterally symmetrical

Total (fully extended) Length: 31mm
Body length: 15mm
Body length (when at shortest): 13mm
Tail length: 16mm
Body width: 2mm
Tail width: <1mm, about 1/3 of a mm

Things I would like to know:
- does the outer portion of its body have muscular functions or does it just serve for protection/movement?
- what does it eat?
- where does it live?
- in what stage of development is it at or is it fully mature?
- can it see? if not, how does it sense its surroundings?
