Description and Identification
The larvae of different species vary considerably. For instance, Calyptra minuticornis is olive-grey and has black-bordered yellow spots all over its body. All larvae have three sets of pro-legs and are generally 3.5 cm long.
Sexual Dimorphism: Present. However, the differences are not prominent.
Color and Appearance
Forewings: When opened, the wings are a light brown with dark brown bands. The wings resemble dried leaves. When closed, the postmedian line becomes visible across both wings.
Hindwings: When opened, they are a grayish brown. This gray color is no longer visible when closed.
Average wingspan: 3.3-4 cm
Flight pattern: Consistent
Season: June to September
After maturing, the larvae begin to pupate.
Male moths pass on the blood they consume to the female as a “gift” during mating. She then gives the sodium of the blood to the eggs she lays.
|Most species live in the Old World, including China, India, Japan, eastern Africa and Europe, southern Europe, and southeast Asia. The sole exception is the Canadian owlet moth, which inhabits Canada and the U.S.
|Forest edges and scrublands
|Lifespan of Adults
|Males: 2-3 weeks
Females: 3-4 weeks
|Apples, citrus, figs, grapes, mango, pears, plums, raspberries, and strawberries
|Primarily fruit juice and nectars. Only male vampire moths drink blood if available.
Did You Know
- German entomologist Ferdinand Ochsenheimer first described this genus in 1816.
- The proboscis of these moths developed over time to pierce and drink fruits. They use these to drink the blood from their prey as well.
- While the bite of these moths are more severe than mosquitoes, they pose no serious threat to humans.
