Monday Night Mystery

Tonight’s entomological challenge is for the fighting Illini. What is this orange monstrosity?

Points will be awarded as follows to the first person to correctly name:

  1. the structure (4 points)
  2. the family of arthropods to which it belongs (4 points)
  3. the chemicals it produces (1 point each)

The cumulative points winner for the month of February will take home their choice of 1) any 8×10-sized print from my photo galleries, or 2) a guest post here on Myrmecos.

Good luck!

  1. Orange dog horns! Osmeterium, found in the family papilionidae. Looks like different genera secrete different compounds, including monoterpene hydrocarbons, Sesquiterpenes, Aliphatic Acids, and esters (Honda 1980).
