Common Twist

<em>Capua vulgana</em>, commonly known as the common twist, is a small moth in the family Tortricidae within the order Lepidoptera. This species is distributed across temperate regions of Europe, occurring in countries including the United Kingdom, France, Germany, the Netherlands, and Scandinavia. <em>Capua vulgana</em> typically inhabits woodland edges, hedgerows, scrubland, and gardens where its larval host plants are present. The larvae feed on a broad range of deciduous shrubs and trees, including oak (Quercus), hawthorn (Crataegus), blackthorn (Prunus spinosa), and various other woody plants, typically rolling or folding leaves as feeding shelters. Adults are small, with a wingspan of approximately 14 to 19 millimeters, displaying characteristic tortricid-style resting posture with wings held flat over the body. The forewings are pale ochreous to brown with variable darker markings. The species typically produces one generation per year, with adults on the wing from late spring through summer. <em>Capua vulgana</em> is currently assessed as Least Concern by the IUCN, with populations considered stable across its European range. The species is not considered economically significant, though it is related to agricultural pest tortricids. Biological traits such as average adult lifespan, body weight, and precise wing measurements remain poorly documented in the scientific literature.
