Significant variation among families is indicated along the abcissa with an asterisk (*P < , **P < , ***P < ). molts 2 and 3 there was no significant variation among families in relative daily growth. Between molts 3 and 4 there was again significant variation among families (P < , Table I). Between molts 4 and 5 there was no significant variance among families while in the final molt interval the variation among family means was sig- nificant (P < , Table I). As with previous analyses, families 2 and 4 initially exhib- ited low relative growth rates and ultimately became the fastest growing families by the final molt (Fig. 4). Development rate The intermolt interval increased with development. The interval between the first and second molt averaged days while it required about days to proceed from molt 5 to 6 (Fig. 5). The variation among families changed substantially over the course of development. Early in development, between molts 1 and 2, variation among families was highly significant (P < , Table I). This variation was due primarily to the relatively long intermolt period of families 3 and 4 (Fig. 5). The time required to proceed from molt 2 to 3 was virtually identical in all cases; the variation among families was not significant. After the third molt, families 2 and 4 exhibited a large decrease in the intermolt interval relative to the other families. By the final molt interval these two families had an intermolt period 35% lower than the other four fa
