lar′val adj.
Word History: The word larva referring to the newly hatched form of insects before they undergo metamorphosis comes from the Latin word lārva, meaning "evil spirit, ghost, demon." The Latin word also was used to mean "a terrifying mask," such as one that might have been worn by a Roman performer in the role of such an evil spirit. In the 1600s and 1700s, scientists began to use the Latin word to describe the stage in an insect's life during which its final form is still hidden—the larval stage is a mask, so to speak, that the insect will later remove to reveal its adult appearance.

The naturalist includes as one species the several larval stages of the same individual, however much they may differ from each other and from the adult; as he likewise includes the so-called alternate generations of Steenstrup, which can only in a technical sense be considered as the same individual.
Investigations into the effects of OA on marine invertebrates have paid particular attention to larval development (Kurihara et al., 2007; Kurihara, 2008; Miller et al., 2009; Sunday el al., 2011; Doropoulos et al., 2012) because the fate of larvae is linked to settlement and population distribution (Jenkins, 2005; Johnson and Geller, 2006).
Delayed larval development was more pronounced in experiment 1 than in experiment 2 ([LC.sub.50] and [LC.sub.95] values in Table 1).
The pollen collected in the field by stingless bee forager workers is later processed by nurse bees, and is ultimately destined for offspring, composing the larval food.

Abstract--To assess larval fish and egg extrusion through the standard-size mesh plankton net used during resource surveys of the Southeast Area Monitoring and Assessment Program (SEAMAP), 81 bongo tows with side-by-side nets, each constructed with a different mesh size (0.333 mm and 0.202 mm), were taken during 5 SEAMAP surveys conducted in the Gulf of Mexico during 2005-2007.
