Palaearctic distribution, including Iran and Greece; not found in North America north of Mexico. |

Forewing length ranges 10-11mm |
Larva and

Larvae feed on Allium cepa (onion) and A. sativum (garlic).

Description/
Field Marks: |
Forewings tan with variable white or cream colored markings, and at least 2 visible strigulae near apex; can have several more costal strigulae visible. Forewing fringe white or cream with 6-7 tan spots. Hindwing tan and can have either concolorous fringe, or cream colored fringe with 6-7 tan spots. Visible spots (strigulae) on the hindwing and number of visible costal strigulae may be a sexually dimorphic character (male with spots and greater than 3 costal strigulae visible). Males with pectinate antennae. |
| Similar Species: |
- Forewing pattern is distinct, although rubbed specimens may resemble Comadia henrici although this species tends to be slightly larger (male=12-15mm, female 16-20mm) and without the tan spots on the forewing fringe. C. henrici is also known for having the longest epiphysis in the genus, being greater than one half the pro-tibia length. The epiphysis in Dyspess ulula is equal to or slightly less than the length of the pro-tibia. This is a reliable character to distinguish these species.
- Pinned specimens of related species. (Hint: select View by Region on the related species page.)
