May. There is one generation per year. According to estimates, 
this species destroys from 2 to 10 percent of the seed in open- 
grown slash pine stands in northeast Florida each year (514). 
Laspeyresia ingeus Heinrich has been recorded from South 
Carolina, Georgia, Florida, Alabama, and Mississippi and prob- 
ably occurs throughout the range of its favored host, longleaf 
pine. It also infests slash pine to minor extent and may occur 
occasionally on other southern pines. The adult (fig. 147 A) is 
grayish-brown and has a wingspread of 17 to 20 mm. Eggs are 
laid in rows of two to nine eggs each on scale apophyses of 1-year- 
old cones. Young larvae bore downward through the scales and 
enter seeds through the micropyle. Larva feeds during the first 
two instars, each in a seed, vacating it and tunnelling through the 
cone in search of another seed. Before it reaches maturity the 
larva may consume two to five additional seeds. A full-grown 
larva bores into the rachis and usually tunnels toward the base 
for a distance of 1 to 2 inches. Winter is spent in the larval stage 
in this tunnel. Pupation occurs in the spring, usually between 
mid-March and mid-May, and the adult appears about 1 to 2 
weeks later. There is one generation per year, except for occa- 
sional individuals that enter diapause (163). This species causes ~ 
an estimated loss of 21 percent of longleaf pine seed in the Gulf 
States region. The related species, L. erotella (Heinrich) attacks 
loblolly pine cones in the Southeastern States. 
The filbertworm, Melissopus latiferreanus (Wlsm.), occurs 
throughout most of the United States and in southern Canada. 
The larvae feed in hazelnuts, filberts, acorns, beechnuts, chestnuts, 
and oak galls. The adult is reddish-brown and has a wingspread 
of 11 to 20 mm. High percentages of acorn crops may be destroyed 
during poor seed years. 
Paralobesia liriodendrana (Kft.) has been recorded feeding on 
yellow-poplar in New Jersey and on magnolia in Florida. The 
adult is brownish or blackish, and there is a tuft or mass of erect, 
dark-colored scales at the rear of the thorax. Eggs are laid on 
the leaves from May to September. Young larvae bore into the 
mid-vein near the petiole and feed in mines during the first instar. 
Older larvae feed under webs spun on the lower surface of the 
leaves or between two leaves webbed tightly togther. Pupation 
occurs undr the web (593).
