Oak Eggar


Lasiocampa quercus – I came across this striking hairy caterpillar as it crawled over a sea wall when I was on a visit to Llandudno, Wales. They do not feed on oak as the English name leads us to believe, but its cocoon looks much like an acorn. The hairs may cause skin irritation, which is the caterpillar’s defense mechanism. They can grow up to 80mm (3 -1/8in) long.

The larva can take a year to grow in the south, and two years further north where it is cooler. They feed quite rapidly and change appearance as they grow which can make them hard to identify compared to other Eggars. It feeds on a variety of plants, including heather and bramble.

      • I’m sure! I noticed this was taken with a D3200. I have a D3300 that I’ve been wanting to upgrade for a while. Finally decided on the D7500. I think that’s what you use too? Do you like it?

      • I have been using the D7200 for the past couple of years, which is a fabulous camera and which I use all the time now for everything. The D7500 would be an upgrade from this, and looks like a really good camera. Google comparisons before splashing out 🙂

      • Glad you like it! I’ve read that your model is the favorite of the 2 because of the dual memory slots and the extra battery option. But I’m fine without those features. Looking forward to experimenting with it! Your photography is beautiful!
