Hadena perplexa, also known as the tawny shears or pod lover, is a species of moth of the family Noctuidae found in Asia, Europe and North Africa. It was first described, in 1775, by the Austrian lepidopterists Michael Denis and Ignaz Schiffermüller from a type specimen found in the Vienna District of Austria.
The wingspan is 27–36 mm. Forewing olive grey brown or olive ochreous, clouded with darker; claviform stigma large, dark; orbicular and reniform with brown centres and white rings outlined with black; some black toothlike marks before submarginal line; hindwing dirty grey, darker towards termen; the veins dark. This darker form is the usual one throughout Europe; but is replaced in Britain by ochracea Haw. which is pale ochraceous with slightly darker markings; examples with an actually white ground colour are found on the chalk of the South of England, ab. pallida Tutt on the other hand, the darkest forms of ochracea Haw., with few markings but uniform in coloration, are known as brunnea Tutt.

Rare
Under 5% of wildlife watchers report a Tawny Shears sighting in Porto on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 395th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April to June
In those months about 10% of wildlife watchers report a Tawny Shears in Porto on a given day, against under 5% in July to March, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Tawny Shears sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Porto, in our data
Porto is the only city on Wallace's Line with enough records to rate Tawny Shears sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Tawny Shears that you can see in Porto (family Noctuidae, Cutworm Moths and Allies) are Variegated Cutworm Moth (about 20%), Armyworm Moth (about 20%) and Scarce Merveille Du Jour (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tawny Shears is recorded against all the insects logged in Porto (8 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
