The mite Blattisocius mali (Oudemans, 1929), as a new phoretic associate of drosophilid fly Phortica semivirgo (Máca, 1977), is firstly reported from Hungary. The host is known as a potential vector of nematode eyeworm infestation, Thelazia callipaeda Railliet & Henry, 1910.

Fifteen new occurrences of ragweed leaf beetle (Ophraella communa LeSage, 1986) are presented from Hungary based on targeted faunistic investigations and the results of our call for citizen scientists. All records are concentrated on the nearby regions of Budapest, suggesting that the species was introduced to this northern central region of the country by human activity. The high number of new occurrences indicates that the species is steadily established in this region. In contrast, the natural dispersal from the neighbouring southern countries seems not to cross the Hungarian borders yet.

The first Hungarian record of the family Penthaleidae, the occurrence of blue oat mite [Penthaleus cf. major (Dugès, 1837)] in Hungary is presented. This pest mite species was collected on lettuce in greenhouse. Notes to the morphology and the three (cox 1, 18sRNA, ITS2) sequences of the Hungarian specimens are given.
