Observation 71812: Entomophthora syrphi
When: 2011-07-17
Herbarium specimen reported

Notes: This was found on the gills of Lactarius corrugis. At the time the insect was completely enveloped in a mass of conidiophores and conidia as seen in the pictures here. Today however, the condiophores seem to have collapsed and the conidia dispersed allowing me to see the characteristics of the insect host which is about 3-4mm long. I don’t know if this is because the specimen may have dried out a little? I think the insect is Melanostoma mellinum. I thought I’d post these pictures for comment until I can find a description of E. syrphi and compare my observations.

very likely Chymomyza amoena, which is known to frequent mushrooms. the two dark bands on the wings, red eyes and red thorax are diagnostic. knowing the size of the host could be helpful. C. amoena is a third the size of syrphids.
