BIOLOGY: According to Koteja and Howell
(1979), adult females are usually found on the
underside of leaves, and no more than 5 em
above the soil surface. Possibly 2 generations per
year occur in Georgia.
ECONOMIC IMPORTANCE: Of no known
economic importance.
REMARKS: Luzulaspis americana can be
separated from the other American species of
Luzulaspis by the antennae which are distinctly
nearer the front coxae than the anterior end of
the body. Known only from unknown grass,
unknown sedge, and water pennywort
(Hydrocotyle sp.) in Georgia.



Genus MESOLECANIUM Cockerell, 1902b

TYPE SPECIES: Lecanium nocturnum Cocker-
ell and Parrott, 1899.
DESCRIPTION: Body of adult female convex.
Derm becoming heavily sclerotized at maturity.
Discoidal pores on mid-dorsum, extending from
anal plates to above rostrum. Submarginal
tubercles absent. Anal ring with 8 setae. Anten-
nae 5 to 7-segmented. Legs with tibia and tarsus
articulated, partially fused, or completely fused.
Quinquelocular pores in spiracular furrows.
Multilocular pores in vulvar area. Marginal setae
slender, sharply bent near apex. Spiracular setae
in groups of 3, median seta longer than laterals.
NOTES: The only species of Mesolecanium
recorded from the southeastern United States is
M. nigrofasciatum. This is a viviparous species.
The young remain under the female for a short
period of time before moving to the leaves of
their host to settle and feed.

COMMON NAME: terrapin scale


FIELD DESCRIPTION: This scale appears as a
reddish hemispherical insect (Fig. 49) about 2
mm in length, mottled with about 24 radiating
streaks of black which are conspicuous near the
margin. Sometimes the streaks coalesce, forming
a sub-dorsal dark band surrounding a central red
area. Sometimes entirely red or black individuals
are found (Williams and Kosztarab 1972).

DESCRIPTION: (Fig. 50) Adult females nearly
circular, 1.2 mm to 4.2 mm in diameter. DoR-
suMi-Derm becoming heavily sclerotized in
older adult females. Body setae (Fig. 50, C)
sparse, mostly in submarginal area, slender,
slightly curved, apex pointed. Small bilocular
pores (Fig. 50, E) with inner filament scattered
over dorsum. Crown-shaped discoidal pores
(Fig. 50, G) in median row of 9-17 pores extend-
ing from anterior of anal plates, to above
rostrum. Each anal plate (Fig. 50, Hi) triangular
with sclerotized and thickened caudolateral
margin. Derm surrounding anal plates usually
heavily sclerotized. VENTER-Membranous.
Antennae well developed, 6-segmented, (Fig. 50,
L) segment III longest. Submarginal setae (Fig.
50, J) slender, acute, curved, with large base.
Body setae very similar to submarginal setae.
Legs well developed without tibiotarsal scleroses
and free articulation. Spiracular furrows each
with 12 to 47 quinquelocular pores in rows 1 or 2
pores wide, rows may be 3 or4 pores wide near
margin. Multilocular pores (Fig. 50, N) mostly
with 8 loculi. Small microducts (Fig. 50, 0) scat-
tered over venter. MAR.nN- Marginal setae (Fig.
50, B) slender, straight at'base but curved from
about midway to apex. Spiracular setae (Fig. 50,
