Wasp spotted in
Sukhothai. It belongs to the
subfamily Ammophilinae, which members are often
black-yellow or black-red in colours.
They are typically more than 2.5 centimeters long.
Wasps are parasitic on insects and
spiders, and those in
the subfamily Ammophylini build ground
burrows and provision with caterpillars.
Some Thread-waisted Wasps
have been observed lifting their abdomen and perform a kind of dance, as if
they are signaling. See also
