Agromyza alunulata (Hendel, 1931) (Agromyzidae), male (synonym: A. distorta Griffiths, 1955), monophagous leaf miner on Glyceria maxima. A rarely reported species with peculiar anterior spiracles as adaptation to an aquatic environment. Over 200 spiracular bulbs are distributed over the whole surface of each large plate-shaped spiracle. At least the winter puparia end up in water as they are only loosely attached to the leaf surface. Only one further world agromyzid, the East Asian/Japanese rice miner Agromyza oryzae Munakata, 1910, is known with similar anterior spiracles. Summer and winter puparia are dimorphic, a second rare peculiarity among Agromyzidae. Griffiths (Tijdschr. Ent. 106 [1955]: 113-168) observed that larvae can crawl and pupariate underwater being equipped with special bristle-like spines on the ventral locomotory humps. First record for The Netherlands, species known only from Czech Republic, Denmark, England, Finland, France, Germany, Hungary, Lithuania, Poland, Russia, Sweden, and Turkey. 48 papers deal with the species and its parasitoids.
