If
you see a spiny tachina fly, it
will likely grab your attention. They are very large as flies
go. This fly began its life as a parasite when an egg was laid
under the skin of a caterpillar, most likely a tiger
moth caterpillar.
This
view shows why this fly is called
"spiny". As adults these flies live on nectar from flowers.
