you find eggs of a bot fly sticking to the hairs of your horse's ankles. what subfamily do these eggs likely belong to?
bazaltina [42]

Where on find eggs of a Bot Fly sticking to the hairs of your horse's ankles. The subfamily that these eggs likely belong to are: Gasterophilinae.

<h3>What is Gasterophilinae?</h3>

The Gasterophilinae are a subfamily of the Oestridae that comprises huge, parasitic flies; this group was previously classified as a family, but all subsequent classifications locate them squarely within the Oestridae. Many members of this subfamily spend part of their larval lives in herbivore digestive systems.

Gasterophilus intestinalis, often known as the horse bot fly, is a species of insect in the Oestridae family that may be found all over the world. The adults, which resemble bumblebees, are most active throughout the summer.

Female botflies deposit eggs on blood-sucking arthropods like mosquitoes and ticks to reproduce. When afflicted arthropods attack a person or another mammal, larvae from the eggs are released. A botfly larva burrows into subcutaneous tissue after entering the host's skin through a bite wound or a hair follicle.
