Vermitigris

Like many members of Vermileonidae, larva of the is genus will construct pitfall traps. They use these traps to employ a pitfall-feeding strategy that is similar to strategies used by the larval stages of antlions. Their pitfall building behavior is a characteristic behavior for Vermeonids with them being the only known family within diptera whose larvae capture their prey by building pitfall traps in loose substrates.^[2]

This genus is a fly being a part of the order Diptera. It is specifically a Brachyceran fly within the family Vermileonidae, also known as wormlions. There are currently about 13 members of this family with two extinct genera (Protovermileo and Crevermileo). This genus is probably a basal member of the family along with Crevermileo. Evidence for this can be seen with their short mouthparts and fleshy labella.^[2]

This genus currently contains five described species. A list can be found below:

• Vermitigris fairchildi Wheeler, 1930^[1]
• Vermitigris infasciatus Oldroyd, 1947
• Vermitigris orientalis (Brunetti, 1927)^[3]
• Vermitigris sinensis Yang, 1988^[4]
• Vermitigris tsangyanggyatso Shan & Wang, 2026^[2]
