What's the difference between ambrosia and larvae?
Ambrosia
Definition:
(n.) The fabled food of the gods (as nectar was their drink), which conferred immortality upon those who partook of it.
(n.) An unguent of the gods.
(n.) A perfumed unguent, salve, or draught; something very pleasing to the taste or smell.
(n.) Formerly, a kind of fragrant plant; now (Bot.), a genus of plants, including some coarse and worthless weeds, called ragweed, hogweed, etc.

Larvae
Definition:
(pl. ) of Larva
Example Sentences:
(1) Larvae from fresh water eggs, cultured in fresh water and 'normal' laboratory cultures reached 50% infectivity in 3-5 days, losing potential infectivity in 11-15 days post-hatching.
(2) After treatment of larvae of instar 1 at preimago stages about 77% of the insects died.
(3) A total of 3,532 females of various engorged weights was collected from all calves, resulting in a mean female tick yield of 1.78% based on the number of larvae used for all infestations.
(4) Similar concentrations of free ecdysteroids were recorded in adults and larvae, although the two life cycle stages differed in their ratio of ecdysone: 20-hydroxyecdysone.
(5) Larvae of both mutants also excrete 3H-3-hydroxykynurenine and 3H-kynurenine rapidly, which probably accounts for the normal levels of kynurenine during larval life.
(6) Guinea pigs exposed to 200 and 400 H. truncatum larvae elicited the greatest change in feeding efficiency during the fourth infestation.
(7) In cultures of medium ML-15 containing a feeder layer of Dog Sarcoma (DS) cells larvae successfully moulted and showed a small but significant increase in length.
(8) The test is based on the ability of larvae to freely migrate through selected mesh sizes of nylon sieves and the reduced ability of larvae to migrate after preincubation with, and in the presence of, substances that inhibit or reduce larval motility.
(9) This study provides evidence for a maternal yolk factor associated with increased tolerance and resistance of larvae to copper.
(10) Human activity not only increases risk, but influences control by killing mosquito larvae, killing adult mosquitos or preventing mosquitos from feeding.
(11) Infected ticks were reared from larvae feeding on each of 11 rabbits taken from the same site.
(12) Histopathology examination from the margin of the ulcerative area confirmed the diagnosis of basal cell carcinoma, which was infested secondarily with larvae of flies.

(19) Statistical analysis has shown the following: a) the growth inhibition, which is especially distinct in autumn-spring generation, takes place in the Ist instar larvae 1.76-2.20 mm long inhabiting the walls of the nasal cavity and concha (their average body length at hatching is 1.08 plus or minus 0.004 mm); the inhibition is associated with interpopulation relations and apparently does not depend on the date of its beginning and can last from 6 to 7 months; c) after the growth resumption the development continues uninterruptedly up to the moulting; the inhibition is also possible at the beginning of the 2nd instar and then the development proceeds without any intervals up to the complete maturation of larvae.
(20) It is present throughout development and is as abundant in embryos as in larvae and adult flies.
