2020 June 27

 

   It’s a day for giant sawflies (Cimbicidae)   – two photos of cimbicids came within minutes.  First from Gordon Hart from the Highlands area:

 

Giant Birch Sawfly  Trichiosoma triangulum (Hym.: Cimbicidae)  Gordon Hart

   Second is a sawfly larva, photographed by Bonnie Blackwood in the Gorge area, and identified by Libby Avis.  The larva is particularly fond of Honeysuckle, which is where it was found.

   Gordon also sends a picture of a fearsome robber fly.  We are not sure which of two similar species it is – it is possible that the two species may one day be “lumped”.

   Much less fearsome is this bumblebee.  I dare say it has a sting and could use it if it wanted to, but it is a much gentler animal, and I have never heard of someone being stung by one.   Thanks to Annie Pang for the identification.

Jeremy Tatum writes:  Here are photographs of a caterpillar and adult of a pug.  The caterpillar fed on Mahonia.  Some of these pugs are just too difficult to identify, and this is one of them!  Could be Eupithecia maestosa.  But equally could be something else!

   Jeff Gaskin writes:  Today, June 27, I found another California Tortoiseshell in essentially the same spot where I saw one last year and also about the same time of year too.  I found it in Summit Park even though the day was very cloudy and breezy.  Not much else though except for a Lorquin’s Admiral, a Cabbage White and a Western Tiger Swallowtail.
