Field photos of the Honey Mesquite Borer,
Megacyllene robusta Linsley and Chemsak

Adults were active on the lower base and smaller limbs of Prosopis glandulosa. Of over 200 images taken, I felt these two were the best.

  1. WOW! I guess you found the population you were on the edge of! Do you think this is an exceptional year, or that you are just in the right place at the rigtht time?

  2. Actually, this is in an area of old growth Prosopis - locality #2 mentioned in my post(s).

    I can't say for certain whether this is an 'exceptional year' as I've never trapped for them before. I do know that that side of the valley received quite a bit more precip this summer. But, I agree, there is a lot of being 'in the right place at the right time' involved.

    I've quit keeping track of the count but I'm curious how long they will be active. FWS says well into November.

    Thanks for your continued interest and comments, Paul. As always,

    Best wishes, ...

  3. What a magnificent sight. Seeing M. decora here in the east is always a big treat, and it's not nearly as rare as this species.

    Congratulations - persistence pays!

  4. Hey, Ted,

    Thank you.

    From what I'm finding out, these things are more widely distributed in the Sulphur Springs Valley than previously assumed.

    As I mentioned to Paul, above, I don't know if this is just an exceptional year for them or if I fortuitously set my traps out at the right time and right place(s).
