. Annual report of the Nebraska State Horticultural Society. Horticulture -- Nebraska. PARASITISM 131 season. Many of our caterpillars have a dense covering of long hair which, we would suppose, might prove an effective protection by keeping the mother-by at a istance as she seeks a host for her progeny. This is not the case, however, for we find that the wooly-bears, the very hairest of our caterpillars, are very frequently parasitized. The egg is attached to the hair and the young parasite after hatching wriggles down to the skin. It sometimes happens that the caterpillar is almost full grow
. Annual report of the Nebraska State Horticultural Society. Horticulture -- Nebraska. PARASITISM 131 season. Many of our caterpillars have a dense covering of long hair which, we would suppose, might prove an effective protection by keeping the mother-by at a istance as she seeks a host for her progeny. This is not the case, however, for we find that the wooly-bears, the very hairest of our caterpillars, are very frequently parasitized. The egg is attached to the hair and the young parasite after hatching wriggles down to the skin. It sometimes happens that the caterpillar is almost full grown before it is parasitized. In this case the caterpillar may spin its cocoon and even pupate before the parasite develops, but, as stated before, the host never, except possibly in very rare cases, raches the adult stage. The third group of fles parasitic on the larvae of other insects is called Borabjliidae. They are flies which are short and robust, usually with a thick covering of hair which gives them a downy appearance. The wings of many are beautifully mottled with brown or black. They are found most abundant about damp places in the woods, along the roads, or on flowers, and are extremely active in flight, hovering motionless in the air for a moment, then darting away so swiftly the eye cannot follows. Some of the Bombyliidae are parasite in the larvae of moths but the majority choose the larvae of our various wild bees for their A Tachinid fly (Belvosa bifasciata). [After Riley.].
