# Laelapidae

La famiglia Laelapidae comprende circa 650 specie di acari lunghi da 0,5 a 5 mm. Questi aracnidi sono ectoparassiti di insetti o mammiferi. I primi hanno strutture tricoidee deboli sul corpo. Nei secondi queste sono spiniformi e permettono agli acari di agganciarsi agli ospiti. Il piastrone dorsale non è separato in due parti come in alcuni acari.

## Biologia

I maschi trasferiscono lo sperma nelle femmine con i cheliceri. Molte specie si nutrono di linfa o sangue dei mammiferi e depongono le uova nel nido o nella tana dell'ospite. Alcune specie sono vivipare.
Molte specie trasmettono malattie.

## Distribuzione

Cosmopoliti. In vari ambienti: pollai, nidi di piccoli animali, formicai e nello sterco, nei detriti litoranei e nelle derrate immagazzinate.
