andrewjavanjohnson's Identifications

Length 2.5 mm. Differentiated from the very similar X. bispinatus and X. ferrugineus but the lack of a denticle or turbercle at the summit of the declivity on interstriae 1, slightly different arrangement of tubercles on interstriae 3. From sticky panel trap using cubeb lure.

I have been going through and identifying stored specimens that were collected as "bycatch" (non-target species collected) for a 2013 trapping study targeting the redbay ambrosia beetle. These beetles were collected from sticky panel traps with a variety of different lures, swirled in odorless paint thinner to remove most of the tanglefoot, and stored in alcohol.

Length 2.8 mm. Distinguished from the very similar X. ferrugineus by the positions of the declivital tubercles, and the presence of regular interstrial setae on the elytral disc.

Length 1.7 mm, collected from a panel trap with a manuka oil lure. Very happy to find one of these guys in my samples. The arrangement of the frons vestiture (facial hair) of the male is distinctive for this species.

Length 2.3 mm, recovered from xylem galleries in a redbay with symptoms of laurel wilt disease (which will also be recorded separately). The "second wave" of the disease is currently quite active in this area.

Length 1.9 mm. This bark beetle emerged from a dead Darlington oak branch that had come down in recent storms. I always enjoy the "bangs" on the males of this species. A close relative, P. minutissimus, also emerged from the same branch (recorded separately).

In Florida these species are of little consequence, just feeding in dead oak branches. In areas of the country where oak wilt disease is a concern, these are reported to be a potential vector of the fungus.

Length 1.6 mm. This bark beetle emerged from a dead Darlington oak branch that had come down in recent storms. A closely related species, P. pruinosus, also emerged from the same branch (recorded separately). The frons vestiture (facial hair) on the males of this species are oriented more frontward and towards the center of the face.

Length 2.1 mm. I was happy to find a couple of this species (with its distinctively flattened pronotum) in a trap collection - I know that it's been documented in the state, but this is the first time I've found it. Also the first observation of the species on iNaturalist, apparently. From a sticky panel trap with a cubeb oil lure.

Length 1.8 mm. Collected from galleries in twigs from a loblolly pine branch that had fallen to the ground. Distinguished from the very similar P. pinavorus by the punctures on the elytral disc being confused, not arranged into clear linear striae.

Length 5.2 mm. One of four (one male, three female) recovered from phloem galleries in a dead loblolly pine. All three southeastern Ips species were found in the same stem (others recorded separately).

Length 2.4 mm, collected from a panel trap with a cubeb oil lure.

I think I photographed two individuals unless it was the same one that flew to another part of the bathroom.

In Pinecrest Gardens men's restroom before the Florida Native Plant Society's meeting. More info about the Dade Chapter here: https://dade.fnpschapters.org/
