List of arachnids of Ireland

There are approximately 1,107 species of arachnid native to Ireland.^[11] Not up to date for all taxa. Arachnids are eight-legged chelicerate arthropods with pedipalps and bodies divided into two tagmata.

Dicranopalpus ramosus, a harvestman found in southern coastal parts of Ireland.^[1]

Oligolophus tridens, a harvestman found all over Ireland.^[2]

Chelifer cancroides, a pseudoscorpion found in Ireland. The abdomen is short and rounded at the rear, rather than extending into a segmented tail and stinger like a true scorpion, of which there are none in Ireland.^[3]

Ixodes ricinus, the castor bean tick, which spreads the pathogens that cause Lyme disease and tick-borne encephalitis.^[1]

Trombidium holosericeum, a red velvet mite that lives in soil and feeds on insects.^[4]

Pholcus phalangioides, the skull spider, found in County Kerry.^[5]

Egg sac of Ero furcata, a pirate spider found in coastal parts of Ireland.^[6]

Female snake-back spider (Segestria senoculata).^[7]

European cave spider (Meta menardi), recorded in Kerry.

A female Enoplognatha ovata on a Daucus carota; this spider is found in coastal parts of Ireland, especially in the southeast.^[8]

Giant house spider (Eratigena atrica), common in the Midlands.^[9]

Clubiona trivialis, a sac spider very common in the Midlands.^[10]

The most best known and familiar group in Ireland is the spiders, and there are also several species of harvestman (daddy-long-legs), ticks, mites and pseudoscorpions. Arachnid groups absent from Ireland include true scorpions, whip scorpions, solifuges, cave spiders, microwhip scorpions, hooded tick spiders and tarantulas.
