ovis infestions in domestic carnivores might be due to peculiar sheep bot fly preferences and, in general, due to the strong relationship between oestrids and herbivores.

Effect of temperature on pupal development and eclosion dates in the reindeer oestrids Hypoderma tarandi and Cephenemyia trompe (Diptera: Oestridae).
are widespread oestrid flies whose larvae parasitize various cervid hosts, yet attempts to pathologize their significance as well as delineate their taxonomy, dispersal potential, and distribution remain ambiguous.
However, unlike most tachinids, the hosts of most calliphorids (blow flies), oestrids
(bot and warble flies), and sarcophagids (flesh flies) are large vertebrates.
Oestrids were present on the post-calving range in 1993 only.

In 1992, we used sticky traps to catch oestrid flies.
