Explanation of Names
Strauzia noctipennis Stoltzfus 1988
Body length: Male: 5.8-8.0 mm. Female: 6.0-8.1 mm. (Stoltzfus 1988)
Adults are found on the sawtooth sunflower Helianthus grossesrratus. Males have yellow or yellowish brown bodies with dark spots on the mesonotum near wings. Male wings have a very dark coalesced pattern. Females have yellow bodies and may also have small spots on mesonotum. Female wings have an "F" shaped pattern. Female Strauzia noctipennis and Strauzia arculata may be too morphologically similar to identify without genetic data.
Parasitizes the sawtooth sunflower, Helianthus grosseserratus.
Adults are present in June and July. Larvae mine the pith of the plant stems in the fall and pupae overwinter in the root or soil.
Life Cycle
Univoltine life cycle (1 generation per year). Adults meet and mate on their host plant Helianthus grosseserratus in June and July.
Male Strauzia noctipennis can be identified by their dark coalesced wing patterns. Females may be impossible to identify from Strauzia arculata females using morphological characteristics. Both Strauzia noctipennis and Strauzia arculata are found on the sawtooth sunflower Helianthus grosseserratus.
See Also
Strauzia arculata is also found on Helianthus grosseserratus and can be identified by different wing markings. See
Strauzia longipennis varieties look similar to Strauzia noctipennis but are found on a different host plant species, the Jerusalem artichoke Helianthus tuberosus. See
