Nola tutulella is a butterfly ( moth ) from the family of the owl butterflies (Noctuidae).
features
The moths reach a wingspan of 15 to 19 millimeters and are on average smaller than Nola cucullatella . The antennae of the males are double combed, those of the females are thread-like. The labial palps are relatively short, elongated and directed slightly downwards. The head, thorax and wings have a gray basic color. The basal field of the forewings is a little darker in front of the conspicuous inner transverse line, but lighter than in Nola cucullatella . The hind wings are gray. The discal stain is indistinct or missing. The undersides of the forewings are solid brown. The undersides of the hind wings are lighter, dirty gray and marked with a small discal spot.
In the males, the tegumen and the very wide vinculum are relatively short. The tegumen is 1.5 times as long as the vinculum. The saccus (basal part of the valves ) is the longest of the European Nolini species and more than twice as long as that of N. cucullatella . The scaphium , part of the male genital apparatus, is provided with two extremely long, parallel rod-shaped structures. The blades are relatively short. The cucullus ( distal part of the valves) is deeply split and bilobed, the costa and the very short ventral edge are heavily sclerotized , straight and rounded at both tips. The digitus (a sclerotized structure in the distal third of the valve) protrudes and is narrowly triangular. The ventral lobe is drawn out into a small thorn. The saccule is narrow and half as wide as the valve. The ampulla on the right side is angled towards the clasper. It is very broad at the base and almost forked apically . The front process is short and has an angled tip. The rear process is longer, rod-shaped and rounded at the tip. The editum is well developed and is located near the base of the Costa. The transtilla is short and heavily sclerotized. The Juxta is shield-like and deeply split dorsally . The aedeagus is almost straight and eight times as long as it is wide. The cecum is short and narrower than the rest of the aedeagus. The vesica is as wide as the aedeagus and has a large, posterior cornutus, which is toothed at the base and apically pointed.
The ovipositor of the females is short, wide and hairy. The posterior apophyses are slightly longer than the ovipositor. The anterior apophyses, together with the triangular base, are half as long as the eighth abdominal segment . The ostium bursae is almost trapezoidal, heavily sclerotized and is located in the middle of the eighth abdominal segment. The bursal duct is long and heavily sclerotized throughout. In the direction of the corpus bursae of equal length , it is somewhat wider. Signa do not exist. The appendix bursae arises near the anterior end of the ductus bursae.
Similar species
Nola tutulella only resembles N. cucullatella in the drawing of the fore wings in Europe . Genital morphological distinguishing features are the extremely long tip of the saccus; the shape of the almost forked ampulla; the long cornutus, toothed at the base; the shape of the ostium bursae; the long and heavily sclerotized ductus bursae and the lack of signs on the corpus bursae (see here ).
distribution
Nola tutulella is found in mainland Spain and Portugal. Outside of Europe, the species is found in northwest Africa.
biology
Nola tutulella inhabits open or semi-open forest edges, forests and parks with shrubs on which the caterpillars can develop. The moths fly in one generation from June to August and come to light . The pre-imaginal stages are unknown; they probably resemble those of N. cucullatella .
