Monday Night Mystery: Counting Segments

Spread the love

Tonight’s challenge involves this scanning electron micrograph:
mystery3

This is a two part mystery, as follows.

  1. Homology (5 points). Tell me, counting anterior to posterior, which abdominal segment number is “A”.
  2. Taxonomy (5 points). To what family of insects does this specimen belong? To receive full credit, explain how you know this.

The cumulative points winner across all mysteries for the month of May will win their choice of 1) any 8×10-sized print from my insect photography galleries, or 2) a guest post here on Myrmecos.

Good luck!

  1. 4
    Braconidae? Because it looks like one I worked with?
    (I’m fairly sure that’s not a valid answer, but as good as it’s going to get this evening)

  2. 5.
    Platygastridae; the 2nd metasomal tergite looks longer than the rest because it’s 2 fused together.
    I think some scelionids have this feature, too.
