notably Philaeus chrysops Poda (Bonnet 1933), three species of 
Corythalia (Crane 1948) and Phidippus johnsoni Peckham and 
Peckham (Jackson 1978). Female P. chrysops generally had seven 
molts (six instars) before maturity, and this was also true of the 
three species of Corythalia observed by Crane (1948). Jackson 
(1978) reported 6-9 molts for P. johnsoni. Thus, the life cycle of L. 
viridis seems to compare well with those of other salticids. 
Summary 
A population of the salticid spider Lyssomanes viridis (Walcke- 
naer) was sampled for two and one half years on a stand of 
Magnolia grandiflora L. trees in North Florida. Mating took place 
in May and adult males disappeared by mid-June. Females laid 
25-70 eggs per clutch mostly during June. These hatched from June 
to July and the immatures overwintered in middle instars. After 
temperatures increased in the spring the spiders rapidly developed 
to adults. Simple linear regression of the carapace widths indicated 
that this species has a total of seven instars from the end of second 
postembryo through adult female. Males may have one fewer instar. 
L. viridis feeds primarily on Diptera in this habitat.
