List of arachnids of Ireland

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 daisy; 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]

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.

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.
