Calliephialtes Parasite of Codling Moth

DESCRIPTION OF THE SPECIES 
GENERAL description 
The adult female is normally about half an inch long, exclusive of the 
ovipositor, which about equals the body in length. It is of the char¬ 
acteristic pimpline appearance, long and slender, black in color, with the 
legs red and the membranous portions of the venter white. The ovi¬ 
positor is straight for most of its length, but toward the tip curves some¬ 
what ventrally. The male is somewhat shorter and more slender than 
the female, as is commonly the case in this group. 
VARIATION IN SIZE 
There is considerable variation in size, depending upon the abundance 
of suitable larval food, a few individuals of each sex of not more than 
half the normal dimensions having been reared. However, extremely 
diminutive individuals are usually males. 
TECHNICAL DESCRIPTION 
Female. —Length 11 mm.; ovipositor n mm., curving slightly ventrally at the tip; 
abdomen about twice as long as thorax. Head and abdomen black; tegula and a 
small triangular spot on the dorso-posterior angle of the mesonotum pale yellow, and 
a very small spot on the dorsal border of the mesopleurum dark brown; thorax other¬ 
wise black; palpi pale; antennae with two basal segments black, remaining segments 
dark brown; all legs uniform dark fulvous; wings slightly brownish; veins and stigma 
brown. Thorax finely and sparsely punctate; propodeum more coarsely and densely 
punctate, with a shining, impunctate, median depression; abdominal segments

area on the posterior lateral angle. Sheath of ovipositor black, densely hairy; ovi¬

REFERRED 
Calliephialtes messor (Grav.). 
Calliephialtes messor Gravenhorst was originally described in the genus 
Ephialtes in 1821 (1 )* from a unique female from Russia. Dalla Torre (5) 
credits Gravenhorst with having recorded Tinea mellonella as a host of 
this species, but this should be accredited to Taschenberg (2).

Statura, imprimis proportione et tuberculis segmentorum, haec species medium 
tenet inter antecedentem et sequentem; tibiis posticis arcuatis ab utraque differt. 
Longitudo fere 7 linearum. Caput palpis fulvis. Thorax puncto parvo testaceo

squamula stramineis, areola triangulari sessili. Pedes rufofulvi, postici tarsis fuscis,
